WMP: Organizing Files?

Hi all,

I have been trying to help a friend with his music collection. Most of it is mp3 files, and I convinced him to start using WMP. However, he didn't take very good care of his files so they are very disorganized. I I have tried using the configuration in WMP to have it organize the songs he already has using his rip settings, and used 'apply changes to media' (which doesn't get info offline since he has no net connection), but after it gets to 100% some of his songs are still scattered in his music folder instead of being in an artist folder. Help?

Thanks again for any ideas
