lots of dead files on iTunes?

Question

I recently changed the folder that all my music was in. In iTunes, it now shows a double for each song and only one of the two work. When I click on one of the songs that doesn't work, a little exclamation mark inside of a bubble appears next to the song. So my question is, how do i get rid of all the songs that are dead? Is there some way to get rid of all dead files at once? I have way too much music to go through (15Gb)and delete each song.

Answer 1

Delete all of the music from your library (making sure that iTunes doesn't delete the actual files in the process!).

Now add the new music folder to your iTunes library again.
