why can't I get my music out of windows media player?

[EVERYONE deserves ReSpEcT]

I want to backup my library because I'm having trouble with my computer. I click select all and try to drag them to my external drive, but it has a circle with a line through it. They wont copy, how can I get them out!?

 

[Metallica Junkie]

You gotta right click on the song and click "Open file location" and take them outta the file.
