Bulk Rename Utility is an easy to use file rename program (a.k.a. file renamer). Renaming multiple files and/or multiple folders 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.
Rename files according to various criteria, including Regular Expressions and from CSV; Rename photos using EXIF metadata
