Are you tired of spending hours renaming the photographs you just downloaded from your digital camera? Use the power of regular expressions! Give each of your photographs a unique number based on your camera's sequence number. You only have to set up the program once and you can automatically rename all files from it. This utility can be used directly from the command line, it can be used in batch files. Also add it to your Windows Explorer's right click menu for direct access. The program has been written to rename output from my digital camera, but the use of regular expressions makes it so flexible that you will be able to rename pretty much any files. Whether they're generated output from other software or anything else where the filenames have a predictable structure. Stop wasting time and start using RegExpFilerename!
