to bring up the rename UI - media player - plays almost every audio format there is
- audio equalizer - bass boosted
- fix unreliable playback on android - due to phone / app settings
- markdown viewer - and there are two editors
- other tricks
- searching - search by size, date, path/name, mp3-tags, ...
- server config - using arguments or config files, or a mix of both
- zeroconf - announce enabled services on the LAN (pic)

quickstart
just run copyparty-sfx.py -- that's it! ๐
- or install through pypi:
python3 -m pip install --user -U copyparty
- or if you cannot install python, you can use copyparty.exe instead
- or install on arch โฑ on fedora โฑ on NixOS โฑ through nix
- or if you are on android, install copyparty in termux
- or if you prefer to use docker ๐ you can do that too
- docker has all deps built-in, so skip this step:
enable thumbnails (images/audio/video), media indexing, and audio transcoding by installing some recommended deps:
- Alpine:
apk add py3-pillow ffmpeg
- Debian:
apt install python3-pil ffmpeg
- Fedora:
dnf install python3-pillow ffmpeg
- FreeBSD:
pkg install py39-sqlite3 py39-pillow ffmpeg
- MacOS:
port install py-Pillow ffmpeg
- MacOS (alternative):
brew install pillow ffmpeg
- Windows:
python -m pip install --user -U Pillow
- install python and ffmpeg manually; do not use
winget
orMicrosoft Store
(it breaks $PATH) - copyparty.exe comes with
Pillow
and only needsffmpeg
- install python and ffmpeg manually; do not use
- see optional dependencies to enable even more features
running copyparty without arguments (for example doubleclicking it on Windows) will give everyone read/write access to the current folder; you may want accounts and volumes
or see some usage examples for inspiration, or the complete windows example
some recommended options:
-e2dsa
enables general file indexing-e2ts
enables audio metadata indexing (needs either FFprobe or Mutagen)-v /mnt/music:/music:r:rw,foo -a foo:bar
shares/mnt/music
as/music
,r
eadable by anyone, and read-write for userfoo
, passwordbar
- replace
:r:rw,foo
with:r,foo
to only make the folder readable byfoo
and nobody else - see accounts and volumes (or
--help-accounts
) for the syntax and other permissions
- replace
on servers
you may also want these, especially on servers:
- contrib/systemd/copyparty.service to run copyparty as a systemd service (see guide inside)
- contrib/systemd/prisonparty.service to run it in a chroot (for extra security)
- contrib/rc/copyparty to run copyparty on FreeBSD
- contrib/nginx/copyparty.conf to reverse-proxy behind nginx (for better https)
- nixos module to run copyparty on NixOS hosts
and remember to open the ports you want; here's a complete example including every feature copyparty has to offer:
firewall-cmd --permanent --add-port={80,443,3921,3923,3945,3990}/tcp # --zone=libvirt
firewall-cmd --permanent --add-port=12000-12099/tcp --permanent # --zone=libvirt
firewall-cmd --permanent --add-port={1900,5353}/udp # --zone=libvirt
firewall-cmd --reload
(1900:ssdp, 3921:ftp, 3923:http/https, 3945:smb, 3990:ftps, 5353:mdns, 12000:passive-ftp)

testimonials
small collection of user feedback
good enough
, surprisingly correct
, certified good software
, just works
, why
, wow this is better than nextcloud
motivations
project goals / philosophy
- inverse linux philosophy -- do all the things, and do an okay job
- quick drop-in service to get a lot of features in a pinch
- some of the alternatives might be a better fit for you
- run anywhere, support everything
- as many web-browsers and python versions as possible
- every browser should at least be able to browse, download, upload files
- be a good emergency solution for transferring stuff between ancient boxes
- minimal dependencies
- but optional dependencies adding bonus-features are ok
- everything being plaintext makes it possible to proofread for malicious code
- no preparations / setup necessary, just run the sfx (which is also plaintext)
- as many web-browsers and python versions as possible
- adaptable, malleable, hackable
- no build steps; modify the js/python without needing node.js or anything like that
notes
general notes:
- paper-printing is affected by dark/light-mode! use lightmode for color, darkmode for grayscale
- because no browsers currently implement the media-query to do this properly orz
browser-specific:
- iPhone/iPad: use Firefox to download files
- Android-Chrome: increase "parallel uploads" for higher speed (android bug)
- Android-Firefox: takes a while to select files (their fix for โ๏ธ)
- Desktop-Firefox:
may use gigabytes of RAM if your files are massiveseems to be OK now - Desktop-Firefox: may stop you from unplugging USB flashdrives until you visit
about:memory
and clickMinimize memory usage
server-os-specific:
- RHEL8 / Rocky8: you can run copyparty using
/usr/libexec/platform-python
server notes:
- pypy is supported but regular cpython is faster if you enable the database
bugs
- Windows: python 2.7 cannot index non-ascii filenames with
-e2d
- Windows: python 2.7 cannot handle filenames with mojibake
--th-ff-jpg
may fix video thumbnails on some FFmpeg versions (macos, some linux)--th-ff-swr
may fix audio thumbnails on some FFmpeg versions
general bugs
- Windows: if the
up2k.db
(filesystem index) is on a samba-share or network disk, you'll get unpredictable behavior if the share is disconnected for a bit- use
--hist
or thehist
volflag (-v [...]:c,hist=/tmp/foo
) to place the db on a local disk instead
- use
- all volumes must exist / be available on startup; up2k (mtp especially) gets funky otherwise
- probably more, pls let me know
not my bugs
-
Chrome issue 1317069 -- if you try to upload a folder which contains symlinks by dragging it into the browser, the symlinked files will not get uploaded
-
Chrome issue 1352210 -- plaintext http may be faster at filehashing than https (but also extremely CPU-intensive)
-
Firefox issue 1790500 -- entire browser can crash after uploading ~4000 small files

Android: music playback randomly stops due to battery usage settings
-
iPhones: the volume control doesn't work because apple doesn't want it to
- future workaround: enable the equalizer, make it all-zero, and set a negative boost to reduce the volume
- "future" because
AudioContext
can't maintain a stable playback speed in the current iOS version (15.7), maybe one day...

Windows: folders cannot be accessed if the name ends with

- python or windows bug
-
Windows: msys2-python 3.8.6 occasionally throws
RuntimeError: release unlocked lock
when leaving a scoped mutex in up2k- this is an msys2 bug, the regular windows edition of python is fine
-
VirtualBox: sqlite throws
Disk I/O Error
when running in a VM and the up2k database is in a vboxsf- use
--hist

GET
andHEAD
must pass cors validation
- http-api: delete/move is now
1.5.0
(2022-12-03): new chunksize formula for files larger than 128 GiB- users: upgrade to the latest cli uploader if you use that
- devs: update third-party up2k clients (if those even exist)
FAQ
"frequently" asked questions
-
is it possible to block read-access to folders unless you know the exact URL for a particular file inside?
- yes, using the
g
permission, see the examples there - you can also do this with linux filesystem permissions;
chmod 111 music
will make it possible to access files and folders inside themusic
folder but not list the immediate contents -- also works with other software, not just copyparty
- yes, using the
-
can I make copyparty download a file to my server if I give it a URL?
- yes, using hooks
accounts and volumes
per-folder, per-user permissions - if your setup is getting complex, consider making a config file instead of using arguments
- much easier to manage, and you can modify the config at runtime with
systemctl reload copyparty
or more conveniently using the[reload cfg]
button in the control-panel (if the user hasa
/admin in any volume)- changes to the
[global]
config section requires a restart to take effect

eadable by anyone- the syntax is
-v src:dst:perm:perm:...
so local-path, url-path, and one or more permissions to set - granting the same permissions to multiple accounts:
-v .::r,usr1,usr2:rw,usr3,usr4
= usr1/2 read-only, 3/4 read-write
- the syntax is
permissions:

(read): browse folder contents, download files, download as zip/tarw
(write): upload files, move files into this folderm
(move): move files/folders from this folderd
(delete): delete files/foldersg
(get): only download files, cannot see folder contents or zip/tarG
(upget): same asg
except uploaders get to see their own filekeys (seefk
in examples below)a
(admin): can see uploader IPs, config-reload
examples:
- add accounts named u1, u2, u3 with passwords p1, p2, p3:
-a u1:p1 -a u2:p2 -a u3:p3
- make folder
/srv
the root of the filesystem, read-only by anyone:-v /srv::r
- make folder
/mnt/music
available at/music
, read-only for u1 and u2, read-write for u3:-v /mnt/music:music:r,u1,u2:rw,u3
- unauthorized users accessing the webroot can see that the
music
folder exists, but cannot open it

/mnt/ss
available at/i
, read-write for u1, get-only for everyone else, and enable filekeys:-v /mnt/ss:i:rw,u1:g:c,fk=4
c,fk=4
sets thefk
(filekey) volflag to 4, meaning each file gets a 4-character accesskeyu1
can upload files, browse the folder, and see the generated filekeys- other users cannot browse the folder, but can access the files if they have the full file URL with the filekey
- replacing the
g
permission withwg
would let anonymous users upload files, but not see the required filekey to access it - replacing the
g
permission withwG
would let anonymous users upload files, receiving a working direct link in return
anyone trying to bruteforce a password gets banned according to --ban-pw
; default is 24h ban for 9 failed attempts in 1 hour
shadowing
hiding specific subfolders by mounting another volume on top of them
for example -v /mnt::r -v /var/empty:web/certs:r
mounts the server folder /mnt
as the webroot, but another volume is mounted at /web/certs
-- so visitors can only see the contents of /mnt
and /mnt/web
(at URLs /
and /web
), but not /mnt/web/certs
because URL /web/certs
is mapped to /var/empty

- this is only to support MS-DOS PKZIP v2.04g (october 1993) and older
you can also zip a selection of files or folders by clicking them in the browser, that brings up a selection editor and zip button in the bottom right
cool trick: download a folder by appending url-params ?tar&opus
to transcode all audio files (except aac|m4a|mp3|ogg|opus|wma) to opus before they're added to the archive
- super useful if you're 5 minutes away from takeoff and realize you don't have any music on your phone but your server only has flac files and downloading those will burn through all your data + there wouldn't be enough time anyways
- and url-params

/&w
produce jpeg/webm thumbnails/spectrograms instead of the original audio/video/images
uploading
drag files/folders into the web-browser to upload (or use the command-line uploader)
this initiates an upload using up2k
; there are two uploaders available:
[๐] bup
, the basic uploader, supports almost every browser since netscape 4.0[๐] up2k
, the good / fancy one
NB: you can undo/delete your own uploads with [๐งฏ]
unpost
up2k has several advantages:
- you can drop folders into the browser (files are added recursively)
- files are processed in chunks, and each chunk is checksummed
- uploads autoresume if they are interrupted by network issues
- uploads resume if you reboot your browser or pc, just upload the same files again
- server detects any corruption; the client reuploads affected chunks
- the client doesn't upload anything that already exists on the server
- much higher speeds than ftp/scp/tarpipe on some internet connections (mainly american ones) thanks to parallel connections
- the last-modified timestamp of the file is preserved
it is perfectly safe to restart / upgrade copyparty while someone is uploading to it!
all known up2k clients will resume just fine ๐ช
see up2k for details on how it works, or watch a demo video
protip: you can avoid scaring away users with contrib/plugins/minimal-up2k.js which makes it look much simpler
protip: if you enable favicon
in the [โ๏ธ] settings
tab (by typing something into the textbox), the icon in the browser tab will indicate upload progress -- also, the [๐]
and/or [๐]
switches enable visible and/or audible notifications on upload completion
the up2k UI is the epitome of polished inutitive experiences:
- "parallel uploads" specifies how many chunks to upload at the same time
[๐]
analysis of other files should continue while one is uploading[๐ฅ]
shows a simpler UI for faster uploads from slow devices[๐ญ]
ask for confirmation before files are added to the queue[๐]
switch between upload and file-search mode- ignore
[๐]
if you add files by dragging them into the browser
- ignore
and then theres the tabs below it,
[ok]
is the files which completed successfully[ng]
is the ones that failed / got rejected (already exists, ...)[done]
shows a combined list of[ok]
and[ng]
, chronological order[busy]
files which are currently hashing, pending-upload, or uploading- plus up to 3 entries each from
[done]
and[que]
for context
- plus up to 3 entries each from
[que]
is all the files that are still queued
note that since up2k has to read each file twice, [๐] bup
can theoretically be up to 2x faster in some extreme cases (files bigger than your ram, combined with an internet connection faster than the read-speed of your HDD, or if you're uploading from a cuo2duo)
if you are resuming a massive upload and want to skip hashing the files which already finished, you can enable turbo
in the [โ๏ธ] config
tab, but please read the tooltip on that button
file-search
dropping files into the browser also lets you see if they exist on the server
when you drag/drop files into the browser, you will see two dropzones: Upload
and Search
on a phone? toggle the
[๐]
switch green before tapping the big yellow Search button to select your files
the files will be hashed on the client-side, and each hash is sent to the server, which checks if that file exists somewhere
files go into [ok]
if they exist (and you get a link to where it is), otherwise they land in [ng]
- the main reason filesearch is combined with the uploader is cause the code was too spaghetti to separate it out somewhere else, this is no longer the case but now i've warmed up to the idea too much
unpost
undo/delete accidental uploads
you can unpost even if you don't have regular move/delete access, however only for files uploaded within the past --unpost
seconds (default 12 hours) and the server must be running with -e2d
self-destruct
uploads can be given a lifetime, afer which they expire / self-destruct
the feature must be enabled per-volume with the lifetime
upload rule which sets the upper limit for how long a file gets to stay on the server
clients can specify a shorter expiration time using the up2k ui -- the relevant options become visible upon navigating into a folder with lifetimes
enabled -- or by using the life
upload modifier
specifying a custom expiration time client-side will affect the timespan in which unposts are permitted, so keep an eye on the estimates in the up2k ui

you can move files across browser tabs (cut in one tab, paste in another)
batch rename
select some files and press F2
to bring up the rename UI
quick explanation of the buttons,

available functions:
$lpad(text, length, pad_char)
$rpad(text, length, pad_char)
so,
say you have a file named meganeko - Eclipse - 07 Sirius A.mp3
(absolutely fantastic album btw) and the tags are: Album:Eclipse
, Artist:meganeko
, Title:Sirius A
, tn:7
you could use just regex to rename it:
regex
=(.*) - (.*) - ([0-9]{2}) (.*)
format
=(3). (1) - (4)
output
=07. meganeko - Sirius A.mp3
or you could use just tags:
format
=$lpad((tn),2,0). (artist) - (title).(ext)
output
=7. meganeko - Sirius A.mp3
or a mix of both:
regex
=- ([0-9]{2})
format
=(1). (artist) - (title).(ext)
output
=07. meganeko - Sirius A.mp3
the metadata keys you can use in the format field are the ones in the file-browser table header (whatever is collected with -mte
and -mtp
)
media player
plays almost every audio format there is (if the server has FFmpeg installed for on-demand transcoding)
the following audio formats are usually always playable, even without FFmpeg: aac|flac|m4a|mp3|ogg|opus|wav
some hilights:
- OS integration; control playback from your phone's lockscreen (windows // iOS // android)
- shows the audio waveform in the seekbar
- not perfectly gapless but can get really close (see settings + eq below); good enough to enjoy gapless albums as intended
click the play
link next to an audio file, or copy the link target to share it (optionally with a timestamp to start playing from, like that example does)
open the [๐บ]
media-player-settings tab to configure it,
- switches:
[preload]
starts loading the next track when it's about to end, reduces the silence between songs[full]
does a full preload by downloading the entire next file; good for unreliable connections, bad for slow connections[~s]
toggles the seekbar waveform display[/np]
enables buttons to copy the now-playing info as an irc message[os-ctl]
makes it possible to control audio playback from the lockscreen of your device (enables mediasession)[seek]
allows seeking with lockscreen controls (buggy on some devices)[art]
shows album art on the lockscreen[๐ฏ]
keeps the playing song scrolled into view (good when using the player as a taskbar dock)[โ]
shrinks the playback controls
- playback mode:
[loop]
keeps looping the folder[next]
plays into the next folder
- transcode:
[flac]
convertsflac
andwav
files into opus[aac]
convertsaac
andm4a
files into opus[oth]
converts all other known formats into opusaac|ac3|aif|aiff|alac|alaw|amr|ape|au|dfpwm|dts|flac|gsm|it|m4a|mo3|mod|mp2|mp3|mpc|mptm|mt2|mulaw|ogg|okt|opus|ra|s3m|tak|tta|ulaw|wav|wma|wv|xm|xpk
- "tint" reduces the contrast of the playback bar
audio equalizer
bass boosted
can also boost the volume in general, or increase/decrease stereo width (like crossfeed just worse)
has the convenient side-effect of reducing the pause between songs, so gapless albums play better with the eq enabled (just make it flat)
fix unreliable playback on android
due to phone / app settings, android phones may randomly stop playing music when the power saver kicks in, especially at the end of an album -- you can fix it by disabling power saving in the app settings of the browser you use for music streaming (preferably a dedicated one)
markdown viewer
and there are two editors
there is a built-in extension for inline clickable thumbnails;
- enable it by adding
<!-- th -->
somewhere in the doc - add thumbnails with
!th[l](your.jpg)
wherel
means left-align (r
= right-align) - a single line with
---
clears the float / inlining - in the case of README.md being displayed below a file listing, thumbnails will open in the gallery viewer
other notes,
- the document preview has a max-width which is the same as an A4 paper when printed
other tricks
-
you can link a particular timestamp in an audio file by adding it to the URL, such as
&20
/&20s
/&1m20
/&t=1:20

-
enabling the audio equalizer can help make gapless albums fully gapless in some browsers (chrome), so consider leaving it on with all the values at zero
-
get a plaintext file listing by adding
?ls=t
to a URL, or a compact colored one with?ls=v
(for unix terminals) -
if you are using media hotkeys to switch songs and are getting tired of seeing the OSD popup which Windows doesn't let you disable, consider ./contrib/media-osd-bgone.ps1
-
click the bottom-left

to open a javascript prompt for debugging -
files named
.prologue.html
/.epilogue.html
will be rendered before/after directory listings unless--no-logues

will be rendered after directory listings unless--no-readme
(but.epilogue.html
takes precedence)
searching
search by size, date, path/name, mp3-tags, ...
when started with -e2dsa
copyparty will scan/index all your files. This avoids duplicates on upload, and also makes the volumes searchable through the web-ui:
- make search queries by
size
/date
/directory-path
/filename
, or... - drag/drop a local file to see if the same contents exist somewhere on the server, see file-search
path/name queries are space-separated, AND'ed together, and words are negated with a -
prefix, so for example:
- path:
shibayan -bossa
finds all files where one of the folders containshibayan
but filters out any results wherebossa
exists somewhere in the path - name:
demetori styx
gives you good stuff
the raw
field allows for more complex stuff such as ( tags like *nhato* or tags like *taishi* ) and ( not tags like *nhato* or not tags like *taishi* )
which finds all songs by either nhato or taishi, excluding collabs (terrible example, why would you do that)
for the above example to work, add the commandline argument -e2ts
to also scan/index tags from music files, which brings us over to:
server config
using arguments or config files, or a mix of both:
- config files (
-c some.conf
) can set additional commandline arguments; see ./docs/example.conf and ./docs/example2.conf kill -s USR1
(same assystemctl reload copyparty
) to reload accounts and volumes from config files without restarting- or click the
[reload cfg]
button in the control-panel if the user hasa
/admin in any volume - changes to the
[global]
config section requires a restart to take effect
- or click the
zeroconf
announce enabled services on the LAN (pic) -- -z
enables both mdns and ssdp
--z-on
/--z-off
' limits the feature to certain networks
mdns
LAN domain-name and feature announcer
uses multicast dns to give copyparty a domain which any machine on the LAN can use to access it
all enabled services (webdav, ftp, smb) will appear in mDNS-aware file managers (KDE, gnome, macOS, ...)
the domain will be http://partybox.local if the machine's hostname is partybox
unless --name
specifies soemthing else
ssdp
windows-explorer announcer
uses ssdp to make copyparty appear in the windows file explorer on all machines on the LAN
doubleclicking the icon opens the "connect" page which explains how to mount copyparty as a local filesystem
if copyparty does not appear in windows explorer, use --zsv
to see why:
- maybe the discovery multicast was sent from an IP which does not intersect with the server subnets
qr-code
print a qr-code (screenshot) for quick access, great between phones on android hotspots which keep changing the subnet
--qr
enables it--qrs
does https instead of http--qrl lootbox/?pw=hunter2
appends to the url, linking to thelootbox
folder with passwordhunter2
--qrz 1
forces 1x zoom instead of autoscaling to fit the terminal size- 1x may render incorrectly on some terminals/fonts, but 2x should always work
it uses the server hostname if mdns is enbled, otherwise it'll use your external ip (default route) unless --qri
specifies a specific ip-prefix or domain
ftp server
an FTP server can be started using --ftp 3921
, and/or --ftps
for explicit TLS (ftpes)
- based on pyftpdlib
- needs a dedicated port (cannot share with the HTTP/HTTPS API)
- uploads are not resumable -- delete and restart if necessary
- runs in active mode by default, you probably want
--ftp-pr 12000-13000
- if you enable both
ftp
andftps
, the port-range will be divided in half - some older software (filezilla on debian-stable) cannot passive-mode with TLS
- if you enable both
- login with any username + your password, or put your password in the username field
some recommended FTP / FTPS clients; wark
= example password:
- https://winscp.net/eng/download.php
- https://filezilla-project.org/ struggles a bit with ftps in active-mode, but is fine otherwise
- https://rclone.org/ does FTPS with
tls=false explicit_tls=true
lftp -u k,wark -p 3921 127.0.0.1 -e ls
lftp -u k,wark -p 3990 127.0.0.1 -e 'set ssl:verify-certificate no; ls'
webdav server
with read-write support, supports winXP and later, macos, nautilus/gvfs
click the connect button in the control-panel to see connection instructions for windows, linux, macos
general usage:
- login with any username + your password, or put your password in the username field (password field can be empty/whatever)
on macos, connect from finder:
- [Go] -> [Connect to Server...] -> http://192.168.123.1:3923/
in order to grant full write-access to webdav clients, the volflag daw
must be set and the account must also have delete-access (otherwise the client won't be allowed to replace the contents of existing files, which is how webdav works)
connecting to webdav from windows
using the GUI (winXP or later):
- rightclick [my computer] -> [map network drive] -> Folder:
http://192.168.123.1:3923/
- on winXP only, click the
Sign up for online storage
hyperlink instead and put the URL there - providing your password as the username is recommended; the password field can be anything or empty
- on winXP only, click the
known client bugs:
- win7+ doesn't actually send the password to the server when reauthenticating after a reboot unless you first try to login with an incorrect password and then switch to the correct password
- or just type your password into the username field instead to get around it entirely
- connecting to a folder which allows anonymous read will make writing impossible, as windows has decided it doesn't need to login
- workaround: connect twice; first to a folder which requires auth, then to the folder you actually want, and leave both of those mounted
- win7+ may open a new tcp connection for every file and sometimes forgets to close them, eventually needing a reboot
- maybe NIC-related (??), happens with win10-ltsc on e1000e but not virtio
- windows cannot access folders which contain filenames with invalid unicode or forbidden characters (
<>:"/\|?*
), or names ending with.
- winxp cannot show unicode characters outside of some range
- latin-1 is fine, hiragana is not (not even as shift-jis on japanese xp)
smb server
unsafe, slow, not recommended for wan, enable with --smb
for read-only or --smbw
for read-write
click the connect button in the control-panel to see connection instructions for windows, linux, macos
dependencies: python3 -m pip install --user -U impacket==0.10.0
- newer versions of impacket will hopefully work just fine but there is monkeypatching so maybe not
some BIG WARNINGS specific to SMB/CIFS, in decreasing importance:
- not entirely confident that read-only is read-only
- the smb backend is not fully integrated with vfs, meaning there could be security issues (path traversal). Please use
--smb-port
(see below) and prisonparty- account passwords work per-volume as expected, but account permissions are coalesced; all accounts have read-access to all volumes, and if a single account has write-access to some volume then all other accounts also do
- if no accounts have write-access to a specific volume, or if
--smbw
is not set, then writing to that volume from smb should be impossible - will be fixed once impacket v0.11.0 is released
- if no accounts have write-access to a specific volume, or if
- shadowing probably works as expected but no guarantees
- account passwords work per-volume as expected, but account permissions are coalesced; all accounts have read-access to all volumes, and if a single account has write-access to some volume then all other accounts also do
and some minor issues,
- clients only see the first ~400 files in big folders; impacket#1433
- hot-reload of server config (
/?reload=cfg
) does not include the[global]
section (commandline args) - listens on the first IPv4
-i
interface only (default = :: = 0.0.0.0 = all) - login doesn't work on winxp, but anonymous access is ok -- remove all accounts from copyparty config for that to work
- win10 onwards does not allow connecting anonymously / without accounts
- on windows, creating a new file through rightclick --> new --> textfile throws an error due to impacket limitations -- hit OK and F5 to get your file
- python3 only
- slow
known client bugs:
- on win7 only,
--smb1
is much faster than smb2 (default) because it keeps rescanning folders on smb2- however smb1 is buggy and is not enabled by default on win10 onwards
- windows cannot access folders which contain filenames with invalid unicode or forbidden characters (
<>:"/\|?*
), or names ending with.
the smb protocol listens on TCP port 445, which is a privileged port on linux and macos, which would require running copyparty as root. However, this can be avoided by listening on another port using --smb-port 3945
and then using NAT to forward the traffic from 445 to there;
- on linux:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 445 -j REDIRECT --to-port 3945
authenticate with one of the following:
- username
$username
, password$password
- username
$password
, passwordk
file indexing
enables dedup and music search ++
file indexing relies on two database tables, the up2k filetree (-e2d
) and the metadata tags (-e2t
), stored in .hist/up2k.db
. Configuration can be done through arguments, volflags, or a mix of both.
through arguments:
-e2d
enables file indexing on upload-e2ds
also scans writable folders for new files on startup-e2dsa
also scans all mounted volumes (including readonly ones)-e2t
enables metadata indexing on upload-e2ts
also scans for tags in all files that don't have tags yet-e2tsr
also deletes all existing tags, doing a full reindex-e2v
verfies file integrity at startup, comparing hashes from the db-e2vu
patches the database with the new hashes from the filesystem-e2vp
panics and kills copyparty instead--xlink
enables deduplication across volumes
the same arguments can be set as volflags, in addition to d2d
, d2ds
, d2t
, d2ts
, d2v
for disabling:
-v ~/music::r:c,e2ds,e2tsr
does a full reindex of everything on startup-v ~/music::r:c,d2d
disables all indexing, even if any-e2*
are on-v ~/music::r:c,d2t
disables all-e2t*
(tags), does not affect-e2d*
-v ~/music::r:c,d2ds
disables on-boot scans; only index new uploads-v ~/music::r:c,d2ts
same except only affecting tags
note:
e2tsr
is probably always overkill, sincee2ds
/e2dsa
would pick up any file modifications ande2ts
would then reindex those, unless there is a new copyparty version with new parsers and the release note says otherwise- the rescan button in the admin panel has no effect unless the volume has
-e2ds
or higher - deduplication is possible on windows if you run copyparty as administrator (not saying you should!)
exclude-patterns
to save some time, you can provide a regex pattern for filepaths to only index by filename/path/size/last-modified (and not the hash of the file contents) by setting --no-hash \.iso$
or the volflag :c,nohash=\.iso$
, this has the following consequences:
- initial indexing is way faster, especially when the volume is on a network disk
- makes it impossible to file-search
- if someone uploads the same file contents, the upload will not be detected as a dupe, so it will not get symlinked or rejected
similarly, you can fully ignore files/folders using --no-idx [...]
and :c,noidx=\.iso$
if you set --no-hash [...]
globally, you can enable hashing for specific volumes using flag :c,nohash=
filesystem guards
avoid traversing into other filesystems using --xdev
/ volflag :c,xdev
, skipping any symlinks or bind-mounts to another HDD for example
and/or you can --xvol
/ :c,xvol
to ignore all symlinks leaving the volume's top directory, but still allow bind-mounts pointing elsewhere
- symlinks are permitted with
xvol
if they point into another volume where the user has the same level of access
these options will reduce performance; unlikely worst-case estimates are 14% reduction for directory listings, 35% for download-as-tar
as of copyparty v1.7.0 these options also prevent file access at runtime -- in previous versions it was just hints for the indexer
periodic rescan
filesystem monitoring; if copyparty is not the only software doing stuff on your filesystem, you may want to enable periodic rescans to keep the index up to date
argument --re-maxage 60
will rescan all volumes every 60 sec, same as volflag :c,scan=60
to specify it per-volume
uploads are disabled while a rescan is happening, so rescans will be delayed by --db-act
(default 10 sec) when there is write-activity going on (uploads, renames, ...)
upload rules
set upload rules using volflags, some examples:
:c,sz=1k-3m
sets allowed filesize between 1 KiB and 3 MiB inclusive (suffixes:b
,k
,m
,g
):c,df=4g
block uploads if there would be less than 4 GiB free disk space afterwards:c,vmaxb=1g
block uploads if total volume size would exceed 1 GiB afterwards:c,vmaxn=4k
block uploads if volume would contain more than 4096 files afterwards:c,nosub
disallow uploading into subdirectories; goes well withrotn
androtf
::c,rotn=1000,2
moves uploads into subfolders, up to 1000 files in each folder before making a new one, two levels deep (must be at least 1):c,rotf=%Y/%m/%d/%H
enforces files to be uploaded into a structure of subfolders according to that date format- if someone uploads to
/foo/bar
the path would be rewritten to/foo/bar/2021/08/06/23
for example - but the actual value is not verified, just the structure, so the uploader can choose any values which conform to the format string
- just to avoid additional complexity in up2k which is enough of a mess already
- if someone uploads to
:c,lifetime=300
delete uploaded files when they become 5 minutes old
you can also set transaction limits which apply per-IP and per-volume, but these assume -j 1
(default) otherwise the limits will be off, for example -j 4
would allow anywhere between 1x and 4x the limits you set depending on which processing node the client gets routed to
:c,maxn=250,3600
allows 250 files over 1 hour from each IP (tracked per-volume):c,maxb=1g,300
allows 1 GiB total over 5 minutes from each IP (tracked per-volume)
compress uploads
files can be autocompressed on upload, either on user-request (if config allows) or forced by server-config
- volflag
gz
allows gz compression - volflag
xz
allows lzma compression - volflag
pk
forces compression on all files - url parameter
pk
requests compression with server-default algorithm - url parameter
gz
orxz
requests compression with a specific algorithm - url parameter
xz
requests xz compression
things to note,
- the
gz
andxz
arguments take a single optional argument, the compression level (range 0 to 9) - the
pk
volflag takes the optional argumentALGORITHM,LEVEL
which will then be forced for all uploads, for examplegz,9
orxz,0
- default compression is gzip level 9
- all upload methods except up2k are supported
- the files will be indexed after compression, so dupe-detection and file-search will not work as expected
some examples,
-v inc:inc:w:c,pk=xz,0
folder named inc, shared at inc, write-only for everyone, forces xz compression at level 0-v inc:inc:w:c,pk
same write-only inc, but forces gz compression (default) instead of xz-v inc:inc:w:c,gz
allows (but does not force) gz compression if client uploads to/inc?pk
or/inc?gz
or/inc?gz=4
other flags
:c,magic
enables filetype detection for nameless uploads, same as--magic
- needs https://pypi.org/project/python-magic/
python3 -m pip install --user -U python-magic
- on windows grab this instead
python3 -m pip install --user -U python-magic-bin
- needs https://pypi.org/project/python-magic/
database location
in-volume (.hist/up2k.db
, default) or somewhere else
copyparty creates a subfolder named .hist
inside each volume where it stores the database, thumbnails, and some other stuff
this can instead be kept in a single place using the --hist
argument, or the hist=
volflag, or a mix of both:
--hist ~/.cache/copyparty -v ~/music::r:c,hist=-
sets~/.cache/copyparty
as the default place to put volume info, but~/music
gets the regular.hist
subfolder (-
restores default behavior)
note:
- markdown edits are always stored in a local
.hist
subdirectory - on windows the volflag path is cyglike, so
/c/temp
meansC:\temp
but use regular paths for--hist
- you can use cygpaths for volumes too,
-v C:\Users::r
and-v /c/users::r
both work
- you can use cygpaths for volumes too,
metadata from audio files
set -e2t
to index tags on upload
-mte
decides which tags to index and display in the browser (and also the display order), this can be changed per-volume:
-v ~/music::r:c,mte=title,artist
indexes and displays title followed by artist
if you add/remove a tag from mte
you will need to run with -e2tsr
once to rebuild the database, otherwise only new files will be affected
but instead of using -mte
, -mth
is a better way to hide tags in the browser: these tags will not be displayed by default, but they still get indexed and become searchable, and users can choose to unhide them in the [โ๏ธ] config
pane
-mtm
can be used to add or redefine a metadata mapping, say you have media files with foo
and bar
tags and you want them to display as qux
in the browser (preferring foo
if both are present), then do -mtm qux=foo,bar
and now you can -mte artist,title,qux
tags that start with a .
such as .bpm
and .dur
(ation) indicate numeric value
see the beautiful mess of a dictionary in mtag.py for the default mappings (should cover mp3,opus,flac,m4a,wav,aif,)
--no-mutagen
disables Mutagen and uses FFprobe instead, which...
- is about 20x slower than Mutagen
- catches a few tags that Mutagen doesn't
- melodic key, video resolution, framerate, pixfmt
- avoids pulling any GPL code into copyparty
- more importantly runs FFprobe on incoming files which is bad if your FFmpeg has a cve
--mtag-to
sets the tag-scan timeout; very high default (60 sec) to cater for zfs and other randomly-freezing filesystems. Lower values like 10 are usually safe, allowing for faster processing of tricky files
file parser plugins
provide custom parsers to index additional tags, also see ./bin/mtag/README.md
copyparty can invoke external programs to collect additional metadata for files using mtp
(either as argument or volflag), there is a default timeout of 60sec, and only files which contain audio get analyzed by default (see ay/an/ad below)
-mtp .bpm=~/bin/audio-bpm.py
will execute~/bin/audio-bpm.py
with the audio file as argument 1 to provide the.bpm
tag, if that does not exist in the audio metadata-mtp key=f,t5,~/bin/audio-key.py
uses~/bin/audio-key.py
to get thekey
tag, replacing any existing metadata tag (f,
), aborting if it takes longer than 5sec (t5,
)-v ~/music::r:c,mtp=.bpm=~/bin/audio-bpm.py:c,mtp=key=f,t5,~/bin/audio-key.py
both as a per-volume config wow this is getting ugly
but wait, there's more! -mtp
can be used for non-audio files as well using the a
flag: ay
only do audio files (default), an
only do non-audio files, or ad
do all files (d as in dontcare)
- "audio file" also means videos btw, as long as there is an audio stream
-mtp ext=an,~/bin/file-ext.py
runs~/bin/file-ext.py
to get theext
tag only if file is not audio (an
)-mtp arch,built,ver,orig=an,eexe,edll,~/bin/exe.py
runs~/bin/exe.py
to get properties about windows-binaries only if file is not audio (an
) and file extension is exe or dll- if you want to daisychain parsers, use the
p
flag to set processing order-mtp foo=p1,~/a.py
runs before-mtp foo=p2,~/b.py
and will forward all the tags detected so far as json to the stdin of b.py
- option
c0
disables capturing of stdout/stderr, so copyparty will not receive any tags from the process at all -- instead the invoked program is free to print whatever to the console, just using copyparty as a launcherc1
captures stdout only,c2
only stderr, andc3
(default) captures both
- you can control how the parser is killed if it times out with option
kt
killing the entire process tree (default),km
just the main process, orkn
let it continue running until copyparty is terminated
if something doesn't work, try --mtag-v
for verbose error messages
event hooks
trigger a program on uploads, renames etc (examples)
you can set hooks before and/or after an event happens, and currently you can hook uploads, moves/renames, and deletes
there's a bunch of flags and stuff, see --help-hooks
upload events
the older, more powerful approach (examples):
-v /mnt/inc:inc:w:c,mte=+x1:c,mtp=x1=ad,kn,/usr/bin/notify-send
so filesystem location /mnt/inc
shared at /inc
, write-only for everyone, appending x1
to the list of tags to index (mte
), and using /usr/bin/notify-send
to "provide" tag x1
for any filetype (ad
) with kill-on-timeout disabled (kn
)
that'll run the command notify-send
with the path to the uploaded file as the first and only argument (so on linux it'll show a notification on-screen)
note that this is way more complicated than the new event hooks but this approach has the following advantages:
- non-blocking and multithreaded; doesn't hold other uploads back
- you get access to tags from FFmpeg and other mtp parsers
- only trigger on new unique files, not dupes
note that it will occupy the parsing threads, so fork anything expensive (or set kn
to have copyparty fork it for you) -- otoh if you want to intentionally queue/singlethread you can combine it with --mtag-mt 1
handlers
redefine behavior with plugins (examples)
replace 404 and 403 errors with something completely different (that's it for now)
hiding from google
tell search engines you dont wanna be indexed, either using the good old robots.txt or through copyparty settings:
--no-robots
adds HTTP (X-Robots-Tag
) and HTML (<meta>
) headers withnoindex, nofollow
globally- volflag
[...]:c,norobots
does the same thing for that single volume - volflag
[...]:c,robots
ALLOWS search-engine crawling for that volume, even if--no-robots
is set globally
also, --force-js
disables the plain HTML folder listing, making things harder to parse for search engines
themes
you can change the default theme with --theme 2
, and add your own themes by modifying browser.css
or providing your own css to --css-browser
, then telling copyparty they exist by increasing --themes
0. classic dark | 2. flat pm-monokai | 4. vice |
1. classic light | 3. flat light | 5. hotdog stand |
the classname of the HTML tag is set according to the selected theme, which is used to set colors as css variables ++
- each theme generally has a dark theme (even numbers) and a light theme (odd numbers), showing in pairs
- the first theme (theme 0 and 1) is
html.a
, second theme (2 and 3) ishtml.b
- if a light theme is selected,
html.y
is set, otherwisehtml.z
is - so if the dark edition of the 2nd theme is selected, you use any of
html.b
,html.z
,html.bz
to specify rules
see the top of ./copyparty/web/browser.css where the color variables are set, and there's layout-specific stuff near the bottom

reverse-proxy
running copyparty next to other websites hosted on an existing webserver such as nginx, caddy, or apache
you can either:
- give copyparty its own domain or subdomain (recommended)
- or do location-based proxying, using
--rp-loc=/stuff
to tell copyparty where it is mounted -- has a slight performance cost and higher chance of bugs- if copyparty says
incorrect --rp-loc or webserver config; expected vpath starting with [...]
it's likely because the webserver is stripping away the proxy location from the request URLs -- see theProxyPass
in the apache example below
- if copyparty says
some reverse proxies (such as Caddy) can automatically obtain a valid https/tls certificate for you, and some support HTTP/2 and QUIC which could be a nice speed boost
- warning: nginx-QUIC is still experimental and can make uploads much slower, so HTTP/2 is recommended for now
example webserver configs:
- nginx config -- entire domain/subdomain
- apache2 config -- location-based
packages
the party might be closer than you think
arch package
now available on aur maintained by @icxes
fedora package
now available on copr-pypi , maintained autonomously -- track record seems OK
dnf copr enable @copr/PyPI
dnf install python3-copyparty # just a minimal install, or...
dnf install python3-{copyparty,pillow,argon2-cffi,pyftpdlib,pyOpenSSL} ffmpeg-free # with recommended deps
this may also work on RHEL but I'm not paying IBM to verify that
nix package
nix profile install github:9001/copyparty
requires a flake-enabled installation of nix
some recommended dependencies are enabled by default; override the package if you want to add/remove some features/deps
ffmpeg-full
was chosen over ffmpeg-headless
mainly because we need withWebp
(and withOpenmpt
is also nice) and being able to use a cached build felt more important than optimizing for size at the time -- PRs welcome if you disagree ๐
nixos module
for this setup, you will need a flake-enabled installation of NixOS.
{
# add copyparty flake to your inputs
inputs.copyparty.url = "github:9001/copyparty";
# ensure that copyparty is an allowed argument to the outputs function
outputs = { self, nixpkgs, copyparty }: {
nixosConfigurations.yourHostName = nixpkgs.lib.nixosSystem {
modules = [
# load the copyparty NixOS module
copyparty.nixosModules.default
({ pkgs, ... }: {
# add the copyparty overlay to expose the package to the module
nixpkgs.overlays = [ copyparty.overlays.default ];
# (optional) install the package globally
environment.systemPackages = [ pkgs.copyparty ];
# configure the copyparty module
services.copyparty.enable = true;
})
];
};
};
}
copyparty on NixOS is configured via services.copyparty
options, for example:
services.copyparty = {
enable = true;
# directly maps to values in the [global] section of the copyparty config.
# see `copyparty --help` for available options
settings = {
i = "0.0.0.0";
# use lists to set multiple values
p = [ 3210 3211 ];
# use booleans to set binary flags
no-reload = true;
# using 'false' will do nothing and omit the value when generating a config
ignored-flag = false;
};
# create users
accounts = {
# specify the account name as the key
ed = {
# provide the path to a file containing the password, keeping it out of /nix/store
# must be readable by the copyparty service user
passwordFile = "/run/keys/copyparty/ed_password";
};
# or do both in one go
k.passwordFile = "/run/keys/copyparty/k_password";
};
# create a volume
volumes = {
# create a volume at "/" (the webroot), which will
"/" = {
# share the contents of "/srv/copyparty"
path = "/srv/copyparty";
# see `copyparty --help-accounts` for available options
access = {
# everyone gets read-access, but
r = "*";
# users "ed" and "k" get read-write
rw = [ "ed" "k" ];
};
# see `copyparty --help-flags` for available options
flags = {
# "fk" enables filekeys (necessary for upget permission) (4 chars long)
fk = 4;
# scan for new files every 60sec
scan = 60;
# volflag "e2d" enables the uploads database
e2d = true;
# "d2t" disables multimedia parsers (in case the uploads are malicious)
d2t = true;
# skips hashing file contents if path matches *.iso
nohash = "\.iso$";
};
};
};
# you may increase the open file limit for the process
openFilesLimit = 8192;
};
the passwordFile at /run/keys/copyparty/ could for example be generated by agenix, or you could just dump it in the nix store instead if that's acceptable

w3m (0.5.3/macports) | can browse, login, upload at 100kB/s, mkdir/msg |
netsurf (3.10/arch) | is basically ie6 with much better css (javascript has almost no effect) |
opera (11.60/winxp) | OK: thumbnails, image-viewer, zip-selection, rename/cut/paste. NG: up2k, navpane, markdown, audio |
ie4 and netscape 4.0 | can browse, upload with ?b=u , auth with &pw=wark |
ncsa mosaic 2.7 | does not get a pass, pic1 - pic2 |
SerenityOS (7e98457) | hits a page fault, works with ?b=u , file upload not-impl |
client examples
interact with copyparty using non-browser clients
-
javascript: dump some state into a file (two separate examples)
await fetch('//127.0.0.1:3923/', {method:"PUT", body: JSON.stringify(foo)});
var xhr = new XMLHttpRequest(); xhr.open('POST', '//127.0.0.1:3923/msgs?raw'); xhr.send('foo');
-
curl/wget: upload some files (post=file, chunk=stdin)
post(){ curl -F act=bput -F f=@"$1" http://127.0.0.1:3923/?pw=wark;}
post movie.mkv
post(){ curl -H pw:wark -H rand:8 -T "$1" http://127.0.0.1:3923/;}
post movie.mkv
post(){ wget --header='pw: wark' --post-file="$1" -O- http://127.0.0.1:3923/?raw;}
post movie.mkv
chunk(){ curl -H pw:wark -T- http://127.0.0.1:3923/;}
chunk <movie.mkv
-
bash: when curl and wget is not available or too boring
(printf 'PUT /junk?pw=wark HTTP/1.1\r\n\r\n'; cat movie.mkv) | nc 127.0.0.1 3923
(printf 'PUT / HTTP/1.1\r\n\r\n'; cat movie.mkv) >/dev/tcp/127.0.0.1/3923
-
python: u2c.py is a command-line up2k client (webm)
- file uploads, file-search, folder sync, autoresume of aborted/broken uploads
- can be downloaded from copyparty: controlpanel -> connect -> u2c.py
- see ./bin/README.md#u2cpy
-
FUSE: mount a copyparty server as a local filesystem
- cross-platform python client available in ./bin/
- can be downloaded from copyparty: controlpanel -> connect -> partyfuse.py
- rclone as client can give ~5x performance, see ./docs/rclone.md
-
sharex (screenshot utility): see ./contrib/sharex.sxcu
copyparty returns a truncated sha512sum of your PUT/POST as base64; you can generate the same checksum locally to verify uplaods:
b512(){ printf "$((sha512sum||shasum -a512)|sed -E 's/ .*//;s/(..)/\\x\1/g')"|base64|tr '+/' '-_'|head -c44;}
b512 <movie.mkv
you can provide passwords using header PW: hunter2
, cookie cppwd=hunter2
, url-param ?pw=hunter2
, or with basic-authentication (either as the username or password)
NOTE: curl will not send the original filename if you use -T
combined with url-params! Also, make sure to always leave a trailing slash in URLs unless you want to override the filename
folder sync
sync folders to/from copyparty
the commandline uploader u2c.py with --dr
is the best way to sync a folder to copyparty; verifies checksums and does files in parallel, and deletes unexpected files on the server after upload has finished which makes file-renames really cheap (it'll rename serverside and skip uploading)
alternatively there is rclone which allows for bidirectional sync and is way more flexible (stream files straight from sftp/s3/gcs to copyparty, ...), although there is no integrity check and it won't work with files over 100 MiB if copyparty is behind cloudflare
- starting from rclone v1.63 (currently in beta), rclone will also be faster than u2c.py
mount as drive
a remote copyparty server as a local filesystem; go to the control-panel and click connect
to see a list of commands to do that
alternatively, some alternatives roughly sorted by speed (unreproducible benchmark), best first:
- rclone-webdav (25s), read/WRITE (v1.63-beta)
- rclone-http (26s), read-only
- partyfuse.py (35s), read-only
- rclone-ftp (47s), read/WRITE
- davfs2 (103s), read/WRITE, very fast on small files
- win10-webdav (138s), read/WRITE
- win10-smb2 (387s), read/WRITE
most clients will fail to mount the root of a copyparty server unless there is a root volume (so you get the admin-panel instead of a browser when accessing it) -- in that case, mount a specific volume instead
android app
upload to copyparty with one tap
'' ''
the app is NOT the full copyparty server! just a basic upload client, nothing fancy yet
if you want to run the copyparty server on your android device, see install on android
iOS shortcuts
there is no iPhone app, but the following shortcuts are almost as good:
- upload to copyparty (offline) (png) based on the original by Daedren (thx!)
- can strip exif, upload files, pics, vids, links, clipboard
- can download links and rehost the target file on copyparty (see first comment inside the shortcut)
- pics become lowres if you share from gallery to shortcut, so better to launch the shortcut and pick stuff from there
performance
defaults are usually fine - expect 8 GiB/s
download, 1 GiB/s
upload
below are some tweaks roughly ordered by usefulness:
-
-q
disables logging and can help a bunch, even when combined with-lo
to redirect logs to file -
--hist
pointing to a fast location (ssd) will make directory listings and searches faster when-e2d
or-e2t
is set -
--no-hash .
when indexing a network-disk if you don't care about the actual filehashes and only want the names/tags searchable -
--no-htp --hash-mt=0 --mtag-mt=1 --th-mt=1
minimizes the number of threads; can help in some eccentric environments (like the vscode debugger) -
-j0
enables multiprocessing (actual multithreading), can reduce latency to20+80/numCores
percent and generally improve performance in cpu-intensive workloads, for example:- lots of connections (many users or heavy clients)
- simultaneous downloads and uploads saturating a 20gbps connection
...however it adds an overhead to internal communication so it might be a net loss, see if it works 4 u
-
using pypy instead of cpython can be 70% faster for some workloads, but slower for many others
- and pypy can sometimes crash on startup with
-j0
(TODO make issue)
- and pypy can sometimes crash on startup with
client-side
when uploading files,
-
chrome is recommended, at least compared to firefox:
- up to 90% faster when hashing, especially on SSDs
- up to 40% faster when uploading over extremely fast internets
- but u2c.py can be 40% faster than chrome again
-
if you're cpu-bottlenecked, or the browser is maxing a cpu core:
- up to 30% faster uploads if you hide the upload status list by switching away from the
[๐]
up2k ui-tab (or closing it)- optionally you can switch to the lightweight potato ui by clicking the
[๐ฅ]
- switching to another browser-tab also works, the favicon will update every 10 seconds in that case
- optionally you can switch to the lightweight potato ui by clicking the
- unlikely to be a problem, but can happen when uploding many small files, or your internet is too fast, or PC too slow
- up to 30% faster uploads if you hide the upload status list by switching away from the
security
there is a discord server with an @everyone
for all important updates (at the lack of better ideas)
some notes on hardening
- set
--rproxy 0
if your copyparty is directly facing the internet (not through a reverse-proxy)- cors doesn't work right otherwise
- if you allow anonymous uploads or otherwise don't trust the contents of a volume, you can prevent XSS with volflag
nohtml
safety profiles:
-
option
-s
is a shortcut to set the following options:--no-thumb
disables thumbnails and audio transcoding to stop copyparty from runningFFmpeg
/Pillow
/VIPS
on uploaded files, which is a good idea if anonymous upload is enabled--no-mtag-ff
usesmutagen
to grab music tags instead ofFFmpeg
, which is safer and faster but less accurate--dotpart
hides uploads from directory listings while they're still incoming--no-robots
and--force-js
makes life harder for crawlers, see hiding from google
-
option
-ss
is a shortcut for the above plus:--unpost 0
,--no-del
,--no-mv
disables all move/delete support--hardlink
creates hardlinks instead of symlinks when deduplicating uploads, which is less maintenance- however note if you edit one file it will also affect the other copies
--vague-401
returns a "404 not found" instead of "401 unauthorized" which is a common enterprise meme--ban-404=50,60,1440
ban client for 1440min (24h) if they hit 50 404's in 60min- NB: will ban anyone who enables up2k turbo
--nih
removes the server hostname from directory listings
-
option
-sss
is a shortcut for the above plus:--no-dav
disables webdav support--no-logues
and--no-readme
disables support for readme's and prologues / epilogues in directory listings, which otherwise lets people upload arbitrary (but sandboxed)<script>
tags-lo cpp-%Y-%m%d-%H%M%S.txt.xz
enables logging to disk-ls **,*,ln,p,r
does a scan on startup for any dangerous symlinks
other misc notes:
- you can disable directory listings by giving permission
g
instead ofr
, only accepting direct URLs to files- combine this with volflag
c,fk
to generate filekeys (per-file accesskeys); users which have full read-access will then see URLs with?k=...
appended to the end, andg
users must provide that URL including the correct key to avoid a 404- the default filekey entropy is fairly small so give
--fk-salt
around 30 characters if you want filekeys longer than 16 chars
- the default filekey entropy is fairly small so give
- permissions
wG
lets users upload files and receive their own filekeys, still without being able to see other uploads
- combine this with volflag
gotchas
behavior that might be unexpected
- users without read-access to a folder can still see the
.prologue.html
/.epilogue.html
/README.md
contents, for the purpose of showing a description on how to use the uploader for example - users can submit
<script>
s which autorun for other visitors in a few ways;- uploading a
README.md
-- avoid with--no-readme
- renaming
some.html
to.epilogue.html
-- avoid with either--no-logues
or--no-dot-ren
- the directory-listing embed is sandboxed (so any malicious scripts can't do any damage) but the markdown editor is not
- uploading a
cors
cross-site request config
by default, except for GET
and HEAD
operations, all requests must either:
- not contain an
Origin
header at all - or have an
Origin
matching the server domain - or the header
PW
with your password as value
cors can be configured with --acao
and --acam
, or the protections entirely disabled with --allow-csrf
password hashing
you can hash passwords before putting them into config files / providing them as arguments; see --help-pwhash
for all the details
--ah-alg argon2
enables it, and if you have any plaintext passwords then it'll print the hashed versions on startup so you can replace them
optionally also specify --ah-cli
to enter an interactive mode where it will hash passwords without ever writing the plaintext ones to disk
the default configs take about 0.4 sec and 256 MiB RAM to process a new password on a decent laptop
https
both HTTP and HTTPS are accepted by default, but letting a reverse proxy handle the https/tls/ssl would be better (probably more secure by default)
copyparty doesn't speak HTTP/2 or QUIC, so using a reverse proxy would solve that as well
if cfssl is installed, copyparty will automatically create a CA and server-cert on startup
- the certs are written to
--crt-dir
for distribution, see--help
for the other--crt
options - this will be a self-signed certificate so you must install your
ca.pem
into all your browsers/devices - if you want to avoid the hassle of distributing certs manually, please consider using a reverse proxy
recovering from crashes
client crashes
frefox wsod
firefox 87 can crash during uploads -- the entire browser goes, including all other browser tabs, everything turns white
however you can hit F12
in the up2k tab and use the devtools to see how far you got in the uploads:
-
get a complete list of all uploads, organized by statuts (ok / no-good / busy / queued):
var tabs = { ok:[], ng:[], bz:[], q:[] }; for (var a of up2k.ui.tab) tabs[a.in].push(a); tabs
-
list of filenames which failed:
โvar ng = []; for (var a of up2k.ui.tab) if (a.in != 'ok') ng.push(a.hn.split('<a href=\"').slice(-1)[0].split('\">')[0]); ng
-
send the list of filenames to copyparty for safekeeping:
await fetch('/inc', {method:'PUT', body:JSON.stringify(ng,null,1)})

dependencies
mandatory deps:
jinja2
(is built into the SFX)
optional dependencies
install these to enable bonus features
enable hashed passwords in config: argon2-cffi
enable ftp-server:
- for just plaintext FTP,
pyftpdlib
(is built into the SFX) - with TLS encryption,
pyftpdlib pyopenssl
enable music tags:
- either
mutagen
(fast, pure-python, skips a few tags, makes copyparty GPL? idk) - or
ffprobe
(20x slower, more accurate, possibly dangerous depending on your distro and users)
enable thumbnails of...
- images:
Pillow
and/orpyvips
and/orffmpeg
(requires py2.7 or py3.5+) - videos/audio:
ffmpeg
andffprobe
somewhere in$PATH
- HEIF pictures:
pyvips
orffmpeg
orpyheif-pillow-opener
(requires Linux or a C compiler) - AVIF pictures:
pyvips
orffmpeg
orpillow-avif-plugin
- JPEG XL pictures:
pyvips
orffmpeg
enable smb support (not recommended):
impacket==0.10.0
pyvips
gives higher quality thumbnails than Pillow
and is 320% faster, using 270% more ram: sudo apt install libvips42 && python3 -m pip install --user -U pyvips
optional gpl stuff
some bundled tools have copyleft dependencies, see ./bin/#mtag
these are standalone programs and will never be imported / evaluated by copyparty, and must be enabled through -mtp
configs
sfx
the self-contained "binary" copyparty-sfx.py will unpack itself and run copyparty, assuming you have python installed of course
you can reduce the sfx size by repacking it; see ./docs/devnotes.md#sfx-repack
copyparty.exe
download copyparty.exe (win8+) or copyparty32.exe (win7+)
can be convenient on machines where installing python is problematic, however is not recommended -- if possible, please use copyparty-sfx.py instead
-
copyparty.exe runs on win8 or newer, was compiled on win10, does thumbnails + media tags, and is currently safe to use, but any future python/expat/pillow CVEs can only be remedied by downloading a newer version of the exe
- on win8 it needs vc redist 2015, on win10 it just works
- some antivirus may freak out (false-positive), possibly Avast, AVG, and McAfee
-
dangerous: copyparty32.exe is compatible with windows7, which means it uses an ancient copy of python (3.7.9) which cannot be upgraded and should never be exposed to the internet (LAN is fine)
-
dangerous and deprecated: copyparty-winpe64.exe lets you run copyparty in WinPE and is otherwise completely useless
meanwhile copyparty-sfx.py instead relies on your system python which gives better performance and will stay safe as long as you keep your python install up-to-date
then again, if you are already into downloading shady binaries from the internet, you may also want my minimal builds of ffmpeg and ffprobe which enables copyparty to extract multimedia-info, do audio-transcoding, and thumbnails/spectrograms/waveforms, however it's much better to instead grab a recent official build every once ina while if you can afford the size
install on android
install Termux + its companion app Termux:API
(see ocv.me/termux) and then copy-paste this into Termux (long-tap) all at once:
yes | pkg upgrade && termux-setup-storage && yes | pkg install python termux-api && python -m ensurepip && python -m pip install --user -U copyparty && { grep -qE 'PATH=.*\.local/bin' ~/.bashrc 2>/dev/null || { echo 'PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc && . ~/.bashrc; }; }
echo $?
after the initial setup, you can launch copyparty at any time by running copyparty
anywhere in Termux -- and if you run it with --qr
you'll get a neat qr-code pointing to your external ip
if you want thumbnails (photos+videos) and you're okay with spending another 132 MiB of storage, pkg install ffmpeg && python3 -m pip install --user -U pillow
- or if you want to use
vips
for photo-thumbs instead,pkg install libvips && python -m pip install --user -U wheel && python -m pip install --user -U pyvips && (cd /data/data/com.termux/files/usr/lib/; ln -s libgobject-2.0.so{,.0}; ln -s libvips.so{,.42})
reporting bugs
ideas for context to include in bug reports
in general, commandline arguments (and config file if any)
if something broke during an upload (replacing FILENAME with a part of the filename that broke):
journalctl -aS '48 hour ago' -u copyparty | grep -C10 FILENAME | tee bug.log
if there's a wall of base64 in the log (thread stacks) then please include that, especially if you run into something freezing up or getting stuck, for example OperationalError('database is locked')
-- alternatively you can visit /?stack
to see the stacks live, so http://127.0.0.1:3923/?stack for example
