The iTunes library is a database iTunes uses to organize your music. Two iTunes library files are created and maintained by iTunes for different purposes. They're both in the iTunes folder.
/Users/username/Music/iTunes/iTunes Music Library.xml
\Documents and Settings\username\My Documents\My Music\iTunes\iTunes Library.itl
\Documents and Settings\username\My Documents\My Music\iTunes\iTunes Music Library.xml
iTunes Music Library.xml
This file contains some (but not all) of the same information stored in the iTunes Library file. The purpose of the iTunes Music Library.xml file is to make your music and playlists available to other applications on your computer.
