Then drill down through these subfolders: Game » Localized » Video.
To skip the opening videos, all you have to do is open your Crysis game install folder (by default this would be located at C:\Program Files\Crysis\).
This is especially useful when you're experimenting with config files because it can be a pain waiting for Crysis to plow through all those opening vids every time. What we want to do here is skip all that promo nVidia/Crytek stuff when Crysis first loads so that the you jump immediately to the menu screen.
This method involves hacking one or more of your Crysis game configuration files. If you don't want to be bothered with the whole Crysis console commands / Devmode thing then here's how you can have cheats applied automatically as soon as you load Crysis.
