KDE Connect is amazing. Also works without KDE.

Kde connect is great.

Syncthing

Either Localsend, if you're only interested in that one function, or KDE Connect for the ultimate experience.

Use LocalSend. It's exactly like Apple Airdrop but works on ALL operating systems so no matter what device you have you can easily transfer files.

It's local, secure and open source.

Syncthing for automated syncing (highly reccomend)

https://github.com/schollz/croc for quick and lazy file sends (auto nat & proxy included)

sftp get from phone if it's like one thing (various ssh/sftp apps on gplay and fdroid)

Kdeconnect + dolphin lets you mount your phone

Single file? KDE Connect. A folder? Syncthing

Check out LocalSend. App that let you send things over local WiFi. No server required.

KDEconnect or gsconnect if you're on KDE or Gnome respectively.

I use syncthing all over the place for this sort of thing. I have some sync directories that are multi way synced across multiple devices, others that are one-way drop targets to a specific device, others that are for operations like backing up photos. It's quite excellent with a good sync algorithm that rarely results in conflicts.

LocalSend or KDE Connect. Syncthing if you need to sync files (Like an important documents folder that always needs to be up to date between your PC and Phone)

Localsend

LocalSend has been great for me. It also works over NetBird or Tailscale. The same goes for KDE Connect.

syncthing is the easy option if you have some files you always want to have on both. if you just want to access your desktop files from your phone, I recommend Cx File Explorer for Android, it's a file browser that supports various network file share protocols including Samba and SFTP.

Syncthing!

can recommend KDEConnect it's working surprisingly robust.

In Debian KDE KDEConnect works well. Dont know about suse but can imagine it works there too

EDIT: grammar

KDE Connect is da Bomb

Syncthing, KDE Connect

KDE Connect has been mentioned before. You can supplement this and other tools by using a VPN so that both endpoints can see each other even if the underlying network does not allow this. My preferred solutions are Tailscale (managed, cloud-based) or Headscale (for self-hosting).

Onionshare or syncthing

snapdrop

Use Localsend!

I use a mix of GSConnect/KDEConnect, Warpinator, and Syncthing. I've got a shared "dropoff" folder on Syncthing that lets me easily drop files from one device to another. You're having issues with Warpinator but if you're able to figure out the issue there, that's my second go-to for one-time file transfers. KDEConnect is a bit more fiddly, but I use it mostly for sharing clipboard info and the occasional file when it's stable enough.

Warpinator. I use it all the time, set a password, make sure you're connected to Wi-Fi and you are all set.

If you are on same network you can use

python3 -m http.server

It will launch a http server which will serve all the files in your computer.

See localsend on github

I used KDEConnect in the past but ran into issues where somehow media sent to my phone wasn't saved somehow. Probably some permission issue but I didn't manage to fix it. Also the windows client only allows selection of one file at a time.

Recently I've tried out LocalSend and found it a much smoother experience.

Install an FTP server on your phone. Connect to it via an FTP client on your PC. EZPZ.

I just use Nextcloud as a storage provider on a local computer.

I use rclone and the Round Sync Android client.

Supports a ton of back ends, self hosted, and commercial options. You can transparently encrypt with private keys you control.

I personally use B2 Backblaze for storage.

My phone backs up every night and Round Sync pushes them to B2. On my desktop I can mount as a volume. I can also access my storage from my phone going the other direction.

I've done the same using SFTP if I don't want the overhead of persistent file storage.

It does not support indexing or previews for searching or finding say a photo. You can put whatever you want for data. So I have caches, indexes, and thumbnails that work in Linux. I can't really make use of those on my phone though.

Rclones bisync feature is also a bit dangerous when I tried to use it a year ago. I more than once "deleted" everything. B2 doesn't delete by default, just hides, so I was able to recover. I now do unidirectional syncs from my machines to different buckets until I'm motivated to investigate a proper 3-way merge solution.

Alternatively, Material Files (available in F-Droid) can easily create a local FTP server or connect to a NAS. It's also a pretty good file manager app.

I have tried KDE connect, and it never works when I need it to. I just send it to myself on Signal. It's the easiest, most non-bullshit way.

If you want just a replacement for Warpinator, LocalSend is definitely the way to go. I used Warpinator before, and LocalSend is just an overall better version of the same thing imo. Finds other devices instantly, can also send text in addition to files and folders, and is available across platforms.
