It's a royal pain in the arse to move all that stuff to the Cameras Library, and rename it all. Then those Libraries get full. I've also tried moving and deleting stuff, and made a mess of that. In the end, the only solution for me was to start over and use PBooost. But then I got Poser 5, and it's ability to use sub-directories, and external Runtimes. I'm much happier now.
