Bulk Rename Utility:
Bulk Rename Utility is an easy to use file rename program (a.k.a. file renamer). Renaming multiple files has never been easier! It has a small memory footprint so it can be left running all the time without consuming all your memory. It started as a freeware Visual Basic tool, but as its popularity has grown it has been completely rewritten in C++ to be robust and lightweight - and very, very fast! It can easily handle folders/discs containing well over 100,000 entries... and it can batch rename 1,000s of files in seconds.
Bulk Rename Utility runs on Windows 7, Windows Vista, Windows XP, Windows Server 2008 and 2003, Windows 2000/NT, 98, Me.
