Windows 7: WMP file corrections not updating in LIBRARIES>MUSIC folders

Greetings

I have WMP 12 on Windows 7. It used to be that if I corrected an album title, song or artist in WMP, it would also correct it in the LIBRARIES> MUSIC folders automatically. There was nothing I needed to do in LIBRARIES> MUSIC folders. This no longer happens.

I had a trojan virus and had to erase everything and restart with backup discs.

NOW if I change an album title in WMP, it does not automatically change the folder name in LIBRARIES> MUSIC as it used to. I have to do it manually.

Also, I get free mp3 downloads from my library. Before the virus, when I would download the mp3, I would just put them in the MUSIC library, and the LIBRARIES> MUSIC folder would automatically create a folder by artist, then subfolder of album, and place the download in the appropriate folder. This no longer happens. I have to do it manually.

How can I correct this to where the LIBRARIES> MUSIC folders update automatically?

Thanks for any help to correct this issue.
