As long as you don't move the geometry folder or folders within the geometry folder (unless you edit the Cr2s to match where you move them), I don't think it matters. (You also have to leave the !DAZ folder at the top of the tree, i.e., wherever it puts it went you install to the default location. Can't remember exactly where that is. I organize the library folders all the time and I never have any problems. (Character, Pose, Props and face). Are you sure it's hanging. If you are using one of the hairs like Yann, they don't render so well with the firefly renderer. Try switching to the Poser4 renderer. (I think they still call it that in Poser5. Anyway, it's the other renderer.)
