Nice find, Joh!Directory Opus
will also show raw files and allow you to do a little bit with them. Of course, it's far more than just a raw viewer, but if you do any sort of file management under Windows it's a superb app and can be an Explorer replacement.
Can be an Explorer replacement! Should be more like.
Probably one of the best bits of software I've ever used. My only criticism is that is not available for the Mac. I have to use Fusion to run Windows to be able to use DOpus, but still quicker/more efficient than using any Mac software.
Go here DOpus info
to get info on what it can do.
