I was copying an iTunes library from one computer to another and copied all the music and then copied the iTunes Music Library.xml file. However, when I did that it ended up with those little exclamation points next to all the songs. It seem it thought all the songs are somewhere else. I went into the advanced settings and made the music folder location where the music was. Is there a way to make it actually look there for the music? It still doesn't know where the music is. Obviously if I try and play one of the songs it asks me to locate the file and I could easily but I don't want to do it a few thousand times, so how can I do it for all the songs at once?
