Brian tried to rename a file and ended up renaming hundreds of them. How can he undo that? Leo says it's a common issue, and if he accidentally hit an asterisk while typing (which is on the 8 key), it could rename everything pretty easily. The good news is that it assigned a number to each duplicate name, so it doesn't overwrite the file. Brian just needs to figure out which file is which. There's an easy fix. Fortunately, Brian uses Carbonite, so he can just restore his backup.
