Rapid File Renamer

Rapid File Renamer enables you to rename large number of files based on specified renaming rules. You can add, remove or replace text in the file name, insert counters and dates, and also change the letter case. The program can independently process both filenames and their extensions. The new filenames can be previewed before they are applied, and you can then choose to replace the original files or create renamed copies in a new folder. Other program features include: processing subfolders, renaming files based on how they are sorted, previewing new filenames, undoing changes, and a warning display when working with important system folders.
