I've read through some of the other batch rename threads, but couldn't find an answer to my problem. Also, I'm using AntRenamer (portable) because I'm uncomfortable using the command line.

Basically, I have a million files named similar to this "John-Smith.jpg" but I need them to look like this "Smith_John.jpg" Any insights would be great!

John-Smith.jpg Smith_John.jpg
