If you have Poser 5, you have no need to put your poses in any other library. In fact, it's a collosal pain in the rear to put your Poses in any other library. You can use subfolders in Poser 5. That helps you better organize your stuff. I use a good file manager program to do that work. You can also create external runtime folders and link to them from Poser 5. And eventually Hogwarden will release a Poser 5 version of PBooost. You'll be in seventh heaven then.
