Poser 4 users can not use "z" files (crz, pzz, hrz, etc). Sure, they could possibly unzip them, but would they know to do this? Or would they simply complain that these are not valid file formats? :) If you're making Poser content, you should think about the trade-off of compressing your files versus supporting Poser 4 users. Is it worth saving 10k if you lose the Poser 4 market? --John
