It's not a good idea for people to release packages that have the MAT Poses in the Camera library. That should be something you choose to do. But even then, there is no longer a need to do that when you have PBooost for Poser 4 (and soon for Poser 5), and Poser 5 has sub directory capabilities. They work like a champ. If you need to rename large amounts of files, get P3DO Explorer, and the Pattern Renamer plugin. You just type in the extension you want changed, and the new extension, and away you go!
