My Poser folder is 4.34 Gigabytes. I save all my installers for all my props and characters, and I pray ;-). I don't know how it got so big, with all the free daz3d give aways since '96, and all the Millennium characters, Poserworld subscription, freestuff, etc... ;-) I guess I could devote an entire 4.7 gig DVD RAM disk to back it up, and it might take several hours.
