MartinC has a Mac to PC and PC to Mac utiity, recently updated somewhere on this site , or at his Rabbit Hole site. It is freeware. I have used it (on a Mac) to convert all types of Poser PC files to Mac with an easy drag and drop operation. It is quick and efficient. Likewise, you can convert Mac to PC by resetting the preferences. Copy the utility and have one set up each way. It is not a large program, but very useful. I think it can only be used on a Mac. -3Don
