Template-Based Command Line File Renaming Utility



rtRenameFiles is a free Windows command line utility that renames all of the files in a directory based on a template. It provides a quick and easy way to bulk-rename files.

I originally wrote this utility for people who are joining large numbers of JPG files together to create timelapse movies. The JPG files need to named in such a way that they will be processed in the right order, so this utility makes it trivial to rename files to their last-modified date. Of couse, this utility will do a lot more than that, so I hope you find it useful.

Feature suggestions are welcome.

Complete documentation is available by clicking the "Documentation" link in the menubar.

This utility was written in PowerBASIC.
