Flash Renamer 4.6
http://www.rlvision.com/flashren/about.asp
I deal with a lot of renaming of clips, pictures, html files, folders, etc....
This does it all, from random naming, to enumerating, adding, cropping.
This program is a serious life savor and works with folders as well...
For people that do a lot of free hosted stuff,.. like we do. This is a must have!
