Last night I had a major glitch that is keeping me from logging into the game, before I try to fix this issue I would like to backup my joystick setting so I can put them back when I get this issue fixed. How do I find and backup this folder ?
While 100Coogn has covered your immediate question with reference to the settings folder, I would add that there are other folders worth backing up if you are in any way thinking of a re-install. e.g. Flims, skins and terrains, even sights if you have made or used some custom ones.
The settings folder is the most user intensive one as it contains all your head position saves, keyboard mapping changes, aircraft/vehilcle loadouts and of course your controller mappings to name a few!
