ok im a nub. i dont know what program runs demos so im trying to look for the program that does so i can watch demos and make them(just incase) so if somone would give me a site to goto to find the program id appreciate it.

you have to play it in the game

with the demo in your firearms folder, go in game and say viewdemo demoname

and then it will play

but when people post deoms on the foums why do they have a download thign? like how do they play the demos that arent theirs?

u just put it in ur game's main folder, like cstrike, and then go into console and play it
