OneDrive
is what my university tutors use for shared storage.
It is possible to use it through the web interface, but it's really tedious as you have to go through 2-factor authentication every time!
On Linux, you can install the (unofficial)
OneDrive for Linux
client, which you can operate entirely from the terminal. If you need to use shared folders, make sure you install a 2.5.x-series version (the version in the Void Linux repository is 2.4.25. You can quite easily package a newer version in xbps-src; it just requires the additional openssl-devel make-dependency).
For setting up, see the
official documentation
. To add a shared folder, use the web interface and select the menu on a shared folder and "Add shortcut to My Files". When you next do a onedrive -s, it should appear in your ~/OneDrive folder.
