What version of Poser do you have? Poser 5 makes it possible to create alternative libraries outside of Poser in any location that you want. Most of my stuff is in the PP 4 library which I can easily access from P5. When that if full I will start storing stuff in other locations, if I ever get to the point where I want to uninstall Pro Pack I can copy the entire runtime library to another directory and do away with the program. Right now, though, until all the P5 bugs are worked out I am keeping it on my system.
