P3Do Explorer is a great tool. It will grab an entire directory for you and switch png's to rsr's or rsr's to png's. Hopefully at some point it will add a feature to delete the old file as well. Saving me a step. :) It does a few other things too but I've yet to try most of them. as for MAC... you should consider buying Virtual PC or Orange PC so you can run PC apps. There's hundreds of them you're missing out on. It's too bad p3do isn't Java though. If it was you could run it on Windows, OSX, Unix, and Linux all using the same compile. (I'm a coder for a java tool called PCGen which gets this benifit by virtue of Java, it really helps us out in the support arena.)

Truth has no value without backing by unfounded belief.
