I take a lot of pictures. This app makes it really easy for me to rename my digital pictures. I like how it gives you a preview before you actually rename them so that you know what it is going to do and how. For this app to be freeware it is very outstanding!!! I would like to see a preset way of renaming files that I can customize that way I don't have to change things back the way I had them every time I open the app up.
