Onr thing is if you never use alot of the junk installed with the original poser install then delete the files. Like the low-ress figures. Folders like "Poser 2 Hi", "Poser 2 Lo", and "Poser 4 Lo". "Characters- Female" and "Characters- Male" whick are over 20 megs each but really are all the same figures. The Poser Install should have had a customize feature! What if I deleted a geometry file for a figure and all I want is to install that file to use? I have to install the whole thing again! If you dont need it, delete it. Just be sure not to delete stuff out of the Geometries folder that you might need for a character you wish to keep to work(probly shouldnt delete anything from the Geometries folder). By the way, my runtime folder is over 2 gigs! Poser Macinstaller has options for an Extra Runtime that items can be installed into but I never could figure it out. Either way the files are still takeing up space, they're just somewhere else on the drive.
