I am trying to split a very large library into separate libraries, but I still add material.
In all of the sublibraries, despite having removed the bulk of items, whenever I perform an auto-import, it analyses all that has ever been in the main big library, which is enough to make any auto-import last a very long time.
What do I need to do to make auto-import forget those items I have removed permanently so the analysation step will be quicker, but I still retain my play stats?
