I'm a "clean freak"! In each of my sole installation of Poser 5, Vue and Brcye 4,I have only the products installed I'm planning to use....when I'm done with them, I move them to a CD Rom. I also store new products I've purchased on CD's until I plan to use them. I have lots of CD Roms and very well organized PC :)

Since I generally install more than one product at a time, I also find that after the first DAZ install, it goes a lot faster (running XP Pro.....a totally stable OS that you can run for a month without rebooting! And more useable than my Linux Mandrake, with its limited software options)
