Maintenance settings control the cleanup of old files, empty subfolders, aging of new files, and the file quota of the folder. Automated cleanups take place as part of the scheduled nightly tasks.
Quotas are always live and enforced immediately.

In the left pane, click FOLDERS. In the list of folders, click the gear icon for the folder. Locate the Change Automated Maintenance Settings section.
Make your selections and click Update Maintenance Settings.
Notes:
Setting Delete empty subfolders after to a value of 0 setting means that no empty subfolders are deleted, even if Cleanup is Enabled.
Every time a file or subfolder is added or removed from a folder, an internal timestamp is updated. Therefore, folders are automatically deleted when they are empty and their internal last activity timestamp is older than the Delete empty subfolders after n days value.
