Very Nice File Renamer

This is a very nice file renamer. I used it to change the extensions on about 4500 files and it workded without a hitch. Looks like it will do up to 100 files at one time. I was changing the extensions on the m4a files in ITunes to m4b to turn them into audio books instead of music files. Worked great.
