PBooost is an essential utility. It's great for Poser 4! PBooost is not yet ready for Poser 5. You can make use of Poser 5's ability to handle sub-diretories. Just use your file manager to make some coherent sense of everything. I made folders for the major characters, then made subdirectories for things like their MAT Pose files, hair, etc. Each time I install something new, I take control and put the items where I want. I also make "themed" CD collections of everything I buy or download (commercial or free stuff). Mike has his own CD's for characters and clothes. So does Vicky, Stephanie, etc. If you want to catalog all that stuff, look for Offline CD Browser, a free program. I forget the link, since I am not at my own computer for awhile.
