I only have about 4 gigs of hard drive and I have Poser 4, Bryce 4, Amorphium, Ray Dream Studio 5, Painter 3D, and numerous other things, and I've never had a problem with my hard drive filling up. I don't keep all my pz3's. If I render something and think it's worth it, I'll save the pz3 on disk, but otherwise, I delete them when I'm finished with them. I do file off onto disk the things I download to free up space. I keep some texture maps that I use frequently in a folder called Posertex and I convert all my renders to jpg, then file off onto disk when my folder gets too much in it. You shouldn't have a problem with 27.4 gigs. Have fun! Melanie
