Batch File Renamer

A fast and easy way to rename files in bulk. Features include an Explore like interface with the ability to sort files in different ways, preview the changes, and undo your most recent rename. You change the file extension, make all file names lower/upper/proper case. Replace, delete or insert characters, add prefixes and suffixes, or replace the names altogether with a sequential name of your choice. By using the check-box before the file names, you can apply different changes to individual files. Click on the Apply button and all of the files with New File Names column filled will be changed. (Update: Added additional features)
