If you have OSX, odds are very, very good that you won't have to touch any of it. Otherwise, only the .png files need anything (everything else is in ASCII format, and OSX can easily handle the silly Windows CR/LF inserts). It's rare that I even have to bother nowadays. I use a dual G5 Mac here; been using raw PC-only stuff in it without a hassle (or even conversion) for ages now (only the really old pre-poser5 PC-only stuff presents any trouble, and all those are w/ the old .rsr files). HTH, /P (PS: may want to ask in the Macintosh forum too if you'd like confirmation).
