iTunes make 2 copies of each song when consolidating...

[JasonReid]

I consolidated my iTunes library because some files were on an external and the rest on the computer and when I did this it made copys of most of the songs in my music folder. Also it didn't consolidate the whole library it still shows many songs on the external.
The actual iTunes library is right, just not all songs point to the computer hard drive.
I have about 100 gigs worth of duplicates that I have no idea how to delete besides doing them one by one.
Any ideas on how to fix this?

This is how my iTunes folder looks for most albums.

That's because you have this checked in iTunes > Preferences > Advanced:

​

To identify the dupes, you could search for "1.mp3" in Finder.

It's one of those preferences that should be auto-deselected. I imagine this causes quite the headache with people with larger music collections...
