How to assign a description to a file

Hello,

Anyway to put a description on a file? either during upload or after upload? and a way to read that description. On OneDrive there is a field for description for the DriveItem object.  Looking on DropBox browser, I see is a comment section.  Maybe a way to add/edit that comment. Not sure if that comment section is part of the DropBox File object.

Thank you
