How to update iTunes library? I moved my old library into the location on Advanced settings.

Why doesn't it display my music???

EDIT:

OSX 1.7.5

iTunes 11.0.2

It is on my local machine.
Just moving your music folder to iTunes library directory won't update your library. You need to add to you Library manually by clicking on File &gt; Add to Library... and selecting your folder (the one you just moved).
Hope I could help.
