Crossfire sound

Hey, i want to add some new sounds to crossfire ex, when you do a headshot it will play HEADSHOOOOT. That file is 1 second long. If I then put in another file that is 8 seconds long but the same name, do it works then?

I have a to do list for u before I explain any shit :

LEARN ENGLISH, I COULD UNDERSTAND BUT IT WAS NO EASY!

yeeeah maybe, maybe not, test it! just back up the original file!
