Black Ops 1 - Random Music *Zombies* - Need help

Hello,

I already had write about a porblem with black ops and "modding", but I opened a new thread, because it is another problem. I like to change the zombie music *easteregg* like 115... I found the files in the "iw_22.iwd" --> sound --> mus --> zombie ... but if i copy the files like 115.wav and try to play the song with my VLC player it woulnd work. I already tried to change the song *convert a mp3 to wav and changed the name to 115.wav and paste it, but it would work D: *

Can somebody help me?

Ohhh ok :P but how are these missing think is called? "only" header?

Okay, thats for exporting the files... but I like to prepare it to import a othersong *converting to a .wav* so that this will be ingame...
But thanks for the export search...
