I believe I've probably tried every other renaming utility out there and, at various times, one or other has had some unique feature that I found useful enough to keep me coming back to that program and not using ABFR. Not any more.! As of version 8 ABFR now appears to have the superset of functions of all other renamers and I need no other program. It's also a bonus that the interface is well thought out and quite easy to master. Some of the other programs are, no doubt, powerful but you need to be a total propellor head to have a fighting chance of getting them to do anything useful. If you are a photographer shooting any sort of volume at all ABFR will pay for itself in a single shoot. Highly recommended.
