I have all my musics in my Internal HDD, and I want to move it to my External. Thing is, all my music, I have organized it myself, and I wanted to move them to the external, not copy them. Is there any risk involving this method? Will my library still point to the music files in my external after I move? I do have another question. When I consolidate library, what does it actually do? Copy exactly the way how I manage my music? Or the copied files managed the way Itunes would manage? Also, in preference, under general, there is a preference stating "Group compilation when browsing." What does this actually do? I tick it and nothing really happened.
