I have a iTunes library, I have been using iTunes library in the external drive as well as internal. Things got messed up and now when I try to play some songs it says it is not available and asks me if I would like the locate the file, but that is too cumbersome to do (it should locate the file by itself! Is there such a function?) I know the files it says are missing are actually still in the internal drive because when I imported the library to another iTunes in another user, it contained all those music files that the other iTunes said was missing. Problem is, the iTunes have a bunch of playlists that took a long time to formulate so I would like to somehow export the playlists without duplicating the song files itself unnecessarily. And then wipe off the iTunes and start from scratch and import the iTunes library and import the playlists without duplication. How do I do this? BTW when you import a library to iTunes file, are you duplicating that file to the detriment of your HDD storage space?
