It works fine. Just make sure that all textures and geometry files that are used in the pz3-file are installed on the computer you move to. Also it may take a bit longer to open the file as Poser has to go looking for textures and obj-files - the paths in the pz3 won't be correct. You might get a dialog box asking you where file so and so is installed. I haven't tried using external morphs though (pmd-files) so I don't know if that would work. Edited to add that once I had a pz3 saved on the Mac that was corrupt when I opened it the next day. The figures dress was floating above her head and it refused to conform properly. I moved the file to my pc and opened it there and everything was well :)
