Reason for keeping good backups #35:
For when your renaming script runs amok and attempts to rename the files it just renamed. Not a particularly common reason for needing backups, but saves me having to work out how to make exiftool work.
In other news, cmd.exe apparently rescans the directory on each iteration of a for loop, such that it will iterate over new files. This can be useful, but not when the point of the loop is to rename files without moving them.
