Wow! Easy and intuitive. It asks permission to rename files in whatever folder you select, asks you to create a file name, and gives you several options, in plain English, for renaming (such as, replace entire file name with numbers, add a prefix or suffix, replace file extension, etc.) It then replaces the name of every file. You can choose the same or a different folder for the next operation. Although it requested future permissions, it asked me each time, so seems safe. I love this app!

The app was working great then went sideways. Now it will only rename one file at a time. Pretty much useless.
