THis has saved me a few times. The first place I look is in the recycle bin. If you have that enabled on your desktop, deleting a file from your device syncs the deletion event to the desktop which puts it in the recycle bin. Sometimes the folder Jason mentions is a good place to get an older version of a file too. I've messed things up beyond usefulness and rather than going to the tape drive backup, I can pull it out of AS's folder backup.
