You don't know how this works? Then you are right here!
So its very simple! You go on you explorer. You go on you Steam Folder (Normaly under: "C:\Program Files (x86)\Steam"), then userdata, then random number its only one folder, then go to "360830" and we are done with the Save Game Location.
It looks something like this.
And then you can edit you files, like this.
I recommended the programm Notepad ++.
