I think that setting sounds more dangerous than it is. A piece in MobileSheets can have multiple images or PDFs. So "All pages in all files" just means all pages in all files of the current piece. It will not touch any files outside of the displayed piece. If you crop a piece while viewing a setlist, another option is available to crop all pieces in the entire setlist - that is arguably a little more dangerous, but it also opens up the ability to clear cropping for every file in the entire library which has been very useful for some users in the past. I can update the wording to say "All pages in all files of current piece" if that is a little clearer.

You can always revert changes to the database by going to Settings->Backup and Restore->Restore Automatic Database Backup. I just wanted to bring that up due to the fact that I don't support an "Undo" type option for most actions.
