I can't find File-Library-Organize on the current version of ITunes. Where is it?

I switched to a different User on Windows 7 and lost most of my Itunes music. I found an option for Itunes to find the lost music. This seemed to work great. All my playlists came back. However, today I learned that it kept all the found music in the other library on a different drive. So, I want to merge this other library into my main one. All the online methods use an option under "File" which does not seem to exist any more.

I have checked the option to consolidate my music but it did not work for the "find lost music" process.

Can anyone help with the current version of Itunes? Or, like the backup, has Apple removed another essential ability?
