Grand Theft Auto 4 (GTA 4)
~installdrive~\Users\~username~\AppData\Local\Rockstar Games\GTA IV\savegames\~user_xxxxxxxxxxxxxxxx~\
Where ~installdrive~ is the volume on which the game is installed, ~username~ is your currently logged on user from which you play, and ~user_xxxxx~ is a uniquely generated xlive save directory.
However, if you are thinking of opening this file in a text editor to quickly change something, you won't have any luck. The file isn't plain text. You'll see what I mean when you open it this way.
Lol i was thinking of opening it with a text editor but of course that would be too easy. So can it be open with something else.
The trouble is i try to change the keyboard mapping in the options the but the keyboard settings go back to the default settings when i go into the game.
No it doesn't look like i am doing it correctly but i have it working now. So i don't know what i did wrong.
