iTunes library, a database which is comprised by all of the music and other media that you add to iTunes, is used to organize and store your music and other media in iTunes. For iPhone/iPad/iPod users, if your PC/ Mac suffers from a system crash or you own a new PC/Mac, Wondershare TunesGo will be able to rebuild your entire iTunes library from your iPhone, iPad and iPod quickly, including Music, Movies, iTunes U, Audiobooks, Podcasts, TV Shows, Music Videos, Home Videos and Playlists.
From the iTunes menu, select File Library Organize Library. Turn on Consolidate files, and if your library is rather old you can also turn on Reorganize files in. If you back up iTunes library to CD/DVD disc, then for restoring iTunes library, you then could follow this: Open iTunes and insert your backup disc.
