Mass Deleting Broken Photo Links In Folders In A Gallery

Long time sytist user.  Im having some drama getting proofs posted.  Most of the 161 folders contained broken links instead of photos in the folders.  Is there a way to delete all folders in a gallery vs deleting them individually so I can re-upload them and hopefully not have them broken this time.  Im sure its an internet issue nothing to do w the software.

If the 161 folders are sub galleries within a gallery, you would need to delete the entire gallery and reupload them. There isn't a batch option to batch delete sub galleries. 

Got it!  Thank you.  I dont want to lose my people who have pre-registered so Ill delete everything one at a time.
