Dropbox

Dropbox on Linux keeps your files in step and little else. If Dropbox is where your life already lives, it will carry on working after you switch.

The one thing to check before you install Linux is the disk format. Dropbox only supports certain ways of formatting a drive, and if the installer you used chose a different one the app will keep complaining that it cannot sync. Most standard installs are fine, but encrypted or unusual setups sometimes are not.

Expect less than the Windows version. Dropbox has never given Linux equal attention, and features arrive late or not at all. If that bothers you, Nextcloud or Syncthing are the alternatives, though neither has Dropbox's sharing links.
