Heya, thanks for the reply.
I know how to share folders

What I meant is, how can Non-Administrator users share them? For example, a
user creates a folder on his computer, puts files in it, and wants to share
that folder.
When he clicks the "Share" button, a consent window pops up, requiring a
computer administrator to put his credentials.
Im assuming that Administrators are part of a group that can share folders.
Or is it something completely different?
I know this should pretty basic...
Thank you in advance.
