Howdy... Just to expand on what you said, Leatherguy... PBooost will work on all windows systems... but can be slightly restricted on XP/2000 when Windows won't let it rename/move library folders sometimes while Poser is running... although the files themselves can be moved/sorted with PBooost with Poser running. However... It has many satisfied users on XP... see the customer feedback for the product!! If you're low on space, PBooost can help you backup folders easily to another drive or CD so you can get at them when you need. Plug Plug. Hope you get back on track! Howard:)
