@Chris una storage already has pruning build in, if file isn't accessed for the certain period of time then the resized images are automatically safely deleted (since they can be automatically recreated upon new access again).

Whether pruning enabled or not can be checked in `sys_objects_transcoder` table:

• atime_tracking - "1" when pruning is enabled
• atime_pruning - if "atime_tracking = 1" then resized files are deleted if they aren't accessed for period of seconds specified in this field (by default 30 days)
