danny_g is correct. You can even have MULTIPLE drives, each with songs in multiple directories on them if you want.
The Tools menu,
Build Songs Database command allows you to select which drives/folders to include in your Songs Database. Just add them into the list window and they will be included.
I suggest you read the Manual on Build Songs Database for a greater understanding. If it's not clear, post back here and we'll get you a better answer... and add to the manual.
