If you often find yourself renaming files I can highly recommend Flash Renamer. It's $20, but it must have saved me thousands of dollars in production time.

Btw, does anybody know of a modern disk usage manager that uses bright, clear individual colors like Space Monger?

As a free alternative to Flash Renamer, PowerRename[0] from the latest PowerToys[1] collection might be worth a look.
