I made a video about copyparty, the selfhosted fileserver I've been making for the past 5 years.

The main focus of the video is the features, but it also touches upon configuration. Was hoping it would be easier to follow than the readme on github... not sure how well that went, but hey :D

This video is also available to watch on the copyparty demo server, as a high-quality AV1 file and a lower-quality h264.

I bumped into copyparty the other month when looking for a software that could let me transfer files to a friend with the ability to pause/resume. Didn't bother with it, tried another software instead. Never really got it to work so I gave up on it.

Bumped into the YouTube video today, decided to give copyparty a shot, damn sir you've written a fine piece of software. It's so easy to get up and configure. The UI is a bit janky, but charming at the same time. Thanks for all the hard work!

Ho... Ly... Shit... This is great! The UI is a bit confusing at first but doesn't take long to get what's going on. I might even be disappointed with a UI revamp 😁 I can't believe how much functionality this has. It's already replacing some processes I have for mounting drives and backing up files. Maybe I missed something, but my only complaint would be the lack of an automatic one-way folder sync in the Party UP! app.

I'm blown away, great job!

Put out some in-depth docker instructions and this will be common use in a month. Good work.

[–] Womble@lemmy.world 3 points 18 hours ago

Yup, I tried to run the docker image with the suggested docker command and it errored out for lack of a config file (though it did offer a fix in the logs for mounting the current directory as read/write)

Well done! This is exactly what I've been looking for! And it's fun to use and has an aesthetic that reminds me of browsing ftp servers back in the day. And these themes?! I love the whimsy mixed with actual usability.

And its a damn good file server so far: fast, easy to use, makes reasonable security choices, and accessible in the ways I want (rclone mount)

[–] utopiah@lemmy.world 11 points 1 day ago

Thanks for making the video but also for providing non Youtube link. Maybe there is a PeerTube server that would enjoy hosting it.

[–] buddascrayon@lemmy.world 15 points 1 day ago (1 children)

Holy shit this is so unbelievably full featured it's not even funny. This is going to rattle some big names. I wonder how long till they try to shut it down because it's better than anything commercially available.

[–] tiramichu@sh.itjust.works 13 points 1 day ago* (last edited 1 day ago)

I haven't even tried it yet, but just from the video you can tell it's going to be insanely good. I'm so impressed.

It's the first bit of software I've seen in a long time where I took one look and immediately thought "Fuck me, I need that!"

I use Unraid for my NAS server and just on the off-chance I checked the Unraid community 'app store' and someone's already created a Docker definition for it, published just today! The hype is real

I'll be giving this a shot

[–] Pall@piefed.social 14 points 1 day ago* (last edited 1 day ago) (1 children)

Is there a way to help translate the UI.

I would like to help translate it into Danish.

Would also be willing to help translate the UI.

this looks amazing! (from the youtube video. also the controls/features seem to be well thought-through) i'll give it a shot tomorrow

[–] Tiger@sh.itjust.works 1 points 16 hours ago

This looks great, nothing to check it out.

[–] piranhaconda@mander.xyz 3 points 22 hours ago

Ok this is too damn cool. Will be checking it out soon, but moving to a new apartment this week so I probably shouldn't dive into new distractions just yet...

[–] sexy_peach@feddit.org 3 points 22 hours ago

OMG I just posted this to lemmy and saw it had already been posted. Great work! Amazing video!!

[–] craftrabbit@lemmy.zip 9 points 1 day ago

Don't believe it. This is easily too good to be true.

[–] LifeInMultipleChoice@lemmy.world 5 points 1 day ago* (last edited 1 day ago) (2 children)

Thank you so very much. I needed to transfer some files locally yesterday and didn't have a NAS set up. So I thought I would quickly set up a samba share on my pop-os media server so my spouse (windows) and I (mint) could swap/store files on the fly in the future. It took me 25 minutes and I almost gave up because my config file was having issues.

This looks sooooo much nicer. May every road rise up to meet you

[–] cravl@slrpnk.net 3 points 19 hours ago (1 children)

I would add PairDrop to your list to have bookmarked. It's completely web-based so no download required and thus fully cross-platform. It also works across different networks (i.e. over the internet) by pairing devices or creating a room. Basically Apple AirDrop, but universal and on steroids.

[–] LifeInMultipleChoice@lemmy.world 1 points 19 hours ago

Bookmarked, thanks. I'll have to try them all out at some point and see what works quickest. Obviously the storage aspect of the poster is a different ball game, but out and about this sounds useful

[–] not@lemmy.dbzer0.com 3 points 23 hours ago (1 children)

For such operations we use LocalSend.

[–] LifeInMultipleChoice@lemmy.world 2 points 22 hours ago

That's for the recommendation. That could be useful as well!

[–] sun@slrpnk.net 6 points 1 day ago

The video are amazing. It's entertaining and explains everything so it's easily understood.

[–] disobey2623@lemmy.dbzer0.com 2 points 22 hours ago (1 children)

I looked at the comparison for Seafile as that's the one I'm most familiar with. In my opinion Seafile's greatest strength is its encryption, but in your comparison you seem to see this as a negative as I assume this bullet refers to the encryption? "isolated on-disk file hierarchy, incompatible with other software. much worse than nextcloud in that regard"

[–] tripflag@lemmy.world 2 points 18 hours ago (1 children)

the intention with that statement was that seafile, by default, places all the files inside its own proprietary file container thing, where the files are not easily accessible from the server's actual filesystem, using regular linux utilities. My knowledge of seafile is really minimal, so this could be wrong -- in which case I'll fix that right away! or, at the very least, try to clarify what I meant to avoid this confusion.

in case you happen to know -- are you aware if it's possible to use Seafile while having it just place all the files and folders on the disk like any other program would?

[–] Andres4NY@social.ridetrans.it 1 points 18 hours ago (1 children)

@tripflag @disobey2623 Your statement is correct; the way seafile stores files is in blocks (for de-duplication, apparently).

They offer a fuse extension that allows you to view stuff like a normal filesystem, though I've never tried it: https://manual.seafile.com/latest/extension/fuse/

[–] disobey2623@lemmy.dbzer0.com 1 points 10 hours ago

And obviously, encrypted folders can't be accessed through the file system even with the fuse add on, because that would break the whole point of encryption.

To me, the one big advantage Seafile has is its e2e encryption and encrypted folders, as it allows me to host it externally without allowing access to my files to the server administrator.

Have been playing around with it for a bit and it's AMAZING.

Guess I'm setting up a locally hosted file server in the near future.

nice project! I'll check it out! I've also really enjoyed your replies here. it's obvious you really know your stuff. thanks!

[–] irmadlad@lemmy.world 1 points 20 hours ago

I'll have to say that this is about one of the most detailed instructions I've seen, replete with copious screenshots. I'm going to have to give it a go just based on that. LOL

[–] LSNLDN@slrpnk.net 4 points 1 day ago (1 children)

This is cool. Idk if it’s just me but the h.264 version of your video has no sound!

[–] tripflag@lemmy.world 5 points 1 day ago (1 children)

man... that's really unexpected, I went with h264+mp3 which should be the most conservative / broadly-supported combination you could possibly use, yet still (ノ ゚ヮ゚)ノ ~┻━┻

what webbrowser / device / player are you using?

[–] LSNLDN@slrpnk.net 5 points 1 day ago* (last edited 1 day ago) (1 children)

This is me browsing slrpnk.net using the voyager app,on iOS latest version on iPhone 14 Pro, it then opens it in whatever built in player the app uses. Other versions work fine though. This app has me excited as I consider starting self hosting!

[–] tripflag@lemmy.world 5 points 1 day ago

awesome thanks, should be able to reproduce it then :>

Every single time I have seen one of your comments, you have disappointed me

I have a question, and I want to emphasise thar this is not criticism but a request for dive into technicalities.

In the video you mentioned copyparty has an one-way sync tool. Is there a good reason why it's not two-way, or is this just something you weren't motivated to do?

[–] tripflag@lemmy.world 14 points 1 day ago (4 children)

No worries, good question :>

The problem with bidirectional filesync is that it's an absolutely massive can of worms, very easy to mess up, and the consequences of messing up are usually the worst kind (loss of data). There's an insane amount of edgecases to keep in mind, and you need to get every edgecase right every single time, otherwise you might wipe someone's vacation photos, or suddenly downgrade someone's keepass database to an older version... And stuff like syncing multiple devices to the same server makes it balloon further.

I've started becoming more confident in copyparty's filesystem-index database, but it's still just a hint/guideline, with the filesystem being the only source of truth -- it's still not something I'd trust with tracking sync-state against one or more clients.

The bigger guys who offer bidirectional sync (nextcloud, syncthing, etc.) have spent years perfecting their logic, so I'd like to leave this in their capable hands.

[–] null_dot@lemmy.dbzer0.com 7 points 1 day ago

Sync is one of those things that seems like it should be trivial but is actually super complicated.
