One of the challenges of sharing Google Drive files is keeping track of who has access to your files. In some cases you might only want someone to have access to the file for a limited time. In those cases you’ll have to remember to go back and change your sharing settings. This week the Google Apps team announced a new solution to that problem.
Over the next couple of months Google will be rolling out a new option to set an expiration date on shared files. You will be able to set specific expiration dates for specific users who have view and or comment access to your Docs, Sheets, and Slides.
