I just use thunar for that.

Again, syncthing is garbage because it has an external dependency. I don't want to transfer a UUID from my fone to my PC. If I have to do that I want to copy it across.
Like, say, via ftp, adb, or rsync. Something where I just have to write "here is my server, it is in the LAN", and that's all the ID needed.
