Question : Problem: Consolidate ITunes Purchases from Multiple Libraries

I have numerous libraries over multiple disks. Some of them contain my ITunes purchases, but none contain all. I would like to re-do my library as I've just consolidated the location of my music files, and that is easy, but I need to know how to find all the libraries and somehow get all the purchases reflected in one library.

Use your search assist( start menue search) and look for the files types in your other drives.
under music Audio/ try a few different files types to search for,also  in the tools folder options view unhide system files.. so your search will look in hidden folders.

Deleting the library and importing it again is about the only way, move the root directory.. copy all your libraries to one folder and point itunes to it
