I'm new to the cd switching, but I think it will work for what i want. I have about 18 gig of music all placed in self extracting files (by group)(I can click them from cd or HD and they go to the proper places), divided between 5 dvd's, I want to use WPI, to install these, so I have choice of which groups are installed. Can it be done? Also a thank you goes out to all who have contributed to the forum, the info here is a goldmine, and Thanks in advance for any input or suggestions.
