Setting expiration dates on files is a good method when file usage should be limited due to copyright or Digital Rights Management (DRM) reasons.
Set Expiration date on a file
Click on the file to view the file in the large preview. Click on the Info icon, to open the edit file window. Clicking the Expiration field will open a calendar. You can select an expiration date for the file on the calendar itself, or type the date into the field.
Find expired files
Once the expiration date passes, the file’s status will change to Expired, and a small red clock icon will be visible just before the file name.
Set Expiration date on multiple files
To edit files in bulk, click the Bulk action icon:
Choose Edit multiple files. Select the files you want to edit. Clicking the “Expiration” field will open a calendar. You can select an expiration date for the file on the calendar itself, or type the date into the field. Click Update files to save the changes.
