Next I installed Rclone and logged in using that, but it seems to be completely command line based which is absolutely useless. There is no way I’m going to sit here typing out full directory paths and file names every time I need to access something (which is always).
I don’t know what file browser you particularly like using. I haven’t used Dropbox (or Mint, for that matter), but it looks like there are various file browsers that have Dropbox support out there.
If you’re using the Cinnamon desktop version of Mint, it looks like the default file browser is called “nemo”. Mint appears to have a package with nemo Dropbox integration called “nemo-dropbox”.
