I have two hard drives: 1.) 20GB C drive for Windows XP and most of my software 2.) 30GB D drive for Poser and all my data (Poser install, artwork and downloads). I redid my installation onto the D drive. I only installed the Michael and Victoria stuff, and any stuff I really wanted to use right away. I think Poser is happier having all the room it wants. I think it's good that Poser doesn't need to fight the Windows Swap File for room. One very important thing: You need to defrag your hard drive frequently. Many people never defrag. Poser seems to suffer more from this neglect. Ron
