The file path should be Appdata\Local\AtC_BB\Saved\SaveGames and you'll find your .sav in there. If you don't know how to get to your appdata, type %appdata% in your search bar.
i know how to get on appdata but when i go i dont see the local atc bb saved saves games folder also i copied the entire folder name and i dont get nothing
You might be in the wrong place? When you open appdata, it'll take you to Appdata/Roaming. You need to backtrack to just the Appdata folder and there you'll find your Local folder.
