Settings file?

Hey, just bought the game off steam and was fiddling with the graphics settings. I set the game to play in a window but forgot to mess with resolution and now the window is too big for me to play properly. I can no longer access the Options tab in the Main menu (due to it being off-screen) and was wondering if I could change the full screen back manually through the file location. Problem is, I can’t seem to find where the settings are saved at. Any help would be much appreciated.

Edit: NVM, problem solved…found it
