1.) Check your Recycle Bin for deleted files.
2.) Double-click some of the music files you have found in that 25GB collection and see if they are playable that way.
You may just have to tell iTunes to rebuild the library.

Duplicate Music Files Finder
Windows XP
I ran this program to clean up my dupe music files, and now much of my iTunes library "can't be located" and pops up the grey exclamation mark icon. I go to the folder of the bands and the subfolders with the album name and they are empty. I probably did something wrong in the execution, but is there anyway to find out what happened or find/recover these files? It looks as though my iTunes library is still taking up the same 25+ GBs of music I used to have, but I can't play any of it.
Any help will be very very appreciated!
