Media Player 9.0 Version guestion

I installed Media Player 9.0 version last night - which worked out fine. I have Windows XP. The problem was that while it was installing it - it also put in all audio files (like audio for money, etc.)

How can I get those files out of Media Player so I just have the music files in that I want to listen to without deleting each and every one individually?

I was also wondering that if I delete those files from Media Player - will they still exist so that when I go into Money, etc. I can listen to instructions?

Also what is the difference between "deleting from playlist" and "deleting from library".

 

media players stock sample music is downloaded into "my docs"/"my music" folder.....if you dont want the clutter of it you can delete from there ,no problem.if you want to keep them just take them out of both playlist and library
