I have three windows laptops at home + 5 android devices, but the main computer where I keep the most important files, is a Linux machine. While using the app on windows + android is the way to go. I managed to upload the files from Linux by drag & drop via browser. Obviously, the manual saving of files is cumbersome and impractical; is there a way to sync directories recursively from Linux using commands (e.g. curl, rsync, etc)?
