If you have P5 then you can put the directories anywhere. I use the download file folder that installs with p5 - I copy this empty runtime to my 120g disk totally devoted to 3d and rename it to suit what I am installing... So far have Men, Kids, Women, House & Outdoors, Industrial & Vehicle, Toons and Animals and My creations. This really works if you use a local drive but I tried it on a lan 100mps and it was like slow death so bought another drive to dedicate to Carrera, Bryce and Poser. However, is real easy to find my stuff now and libraries load really fast! If you are using Poser 4 however, the only way to go is PBoost. I have it on my P4 installation on my old machine and wouldn't be able to find anything without it! Least not in the few years I have left ;-) Plan on taking a few days to get a really large library tamed and be sure to run cross reference program [in freebies] first. Good luck!
