How to consolidate library in itunes 11?. Can't find the option

You can select all of the files in your library (ctrl+a), right-click and choose "consolidate." Unfortunately you'll have to do this for every category separately as far as I can tell (music, movies, apps, etc.).

Oh actually I just found a better way: select the menu icon then "Show menu bar." You can then navigate File>Library>Organize like before.

There used to be auto-consolidation in iTunes 10 (and earlier), and in iTunes 11 Preferences > Advanced you are still offered check-box options for "Keep iTunes Media folder organized" and "Copy files to iTunes Media folder when adding to library", which together should effectively (to my mind) auto-consolidate anything you add to your iTunes library.

However, this seems at least slightly broken in iTunes 11. I ripped some video using Handbrake from DVD to Dekstop, then added it to iTunes, but iTunes was just referencing the files on the Desktop and did not automatically "Copy files to iTunes Media folder when adding to library" as I discovered when I deleted the files from the Desktop and suddenly iTunes couldn't find them anymore!

After re-ripping and re-adding the files to iTunes, I confirmed this by asking iTunes to "Show in Finder", and it showed me the files on the Desktop. Only after using the explicit File > Library > Organize Library command did iTunes finally copy the files to iTunes Media folder.

I have not tried adding new audio files to iTunes 11 yet, so I don't know if this bug (for bug it seems!) affects only video files or all files, etc.

Consolidating files through itunes is one of the dumbest things I have seen. It duplicates all work. So when you want to delete something, it's not deleted. Just fyi. For everyone else reading. I read something about ConsolidateToMove So it doesn't just duplicate, and if you are moving libraries, it makes it that much worse, triplicating it. One of the dumbest additions I say once again.
