:said by Mchart :said by Keizer :The COD5 profile folder is in a different location than COD4. You will find it at: C>Users>Name>AppData>Local>Activision>CaDWaW>Players.
If this folder gets damaged or corrupted, you will lose your weapons and stats.
I always copy mine to a second hard drive every few days.
Not true, everything is stored on the server this go around. While there is a copy stored on your machine - The server keeps a copy as well. If you loose yours it is re-downloaded.
How is it re-downloaded? Automatically? As a test, I just deleted my profile, and started a round, and all my guns and perks were gone. I stuck my backup copy in place, and everything was restored.
I was almost positive the server kept a copy of your rank. Reason being that when the pirated version was leaked, people were talking about how the pirated CD-Key was giving them rank back.
