I have a library for purchase item on the secondary drive already, but how do i set the preference "purchase" item to be stored in the secondary drive, and how do I delete what i loaded on my primary drive? It seems I am making a duplicate, and I was hoping the program was going to ask me where I wanted the item to be loaded. So I closed down the program to keep it from loading more stuff on my limited HD. Where is the files located for the purchase item library?
