all I can say is a cd burner solves all my problems I keep all my wonderful downloads props etc. in a cd archive then I only have on my hard drive what is neccessary based on project. Another note it is good to clean out your libraries as well I mean does anyone really use those old poser 2 models that you get when you install poser? Anyways that is how I keep my memory light, well, that and a lot of drinking :)
