My ultimate answer: 1.) Go over my entire Poser collection, and reorganize everythng properly. I'm talking about the original zip files, etc. Put everything on "themed" cd's (Mike, Vicky, Scenes, etc.) 2.) Run Offline CD Browser to catalog all my new CD's. 3.) Erase my Poser installations. 4.) Start over. Poser 5 allows a real advantage: external Runtimes. I don't install anything in the Poser 5 folder. I install it all in a new folder called "Poser5B." Before I started over, I asked myself what I really used. If I hadn't used something in a few weeks or months, I didn't install it until it was needed, if ever.
