Before major patches, we always advise making a backup your current game settings.
The best way to do this is by copying the Frontier Developments folder and storing it in a safe location. We also advise renaming the folder so that it is clear that it is a backup.
You can duplicate this folder by holding down the "Ctrl" key and dragging the folder to the same directory or a specific back up location.
You can locate the Frontier Developments folder here: C:\Users\%USERNAME%\AppData\Local\
Just drop the location link into your file explorers search bar as shown below. "%USERNAME%" is a wildcard to account for usernames not being the same.
The AppData folder is hidden by default so you may need toggle the 'View Hidden' option in your Username folder first.
Please wait... it will take a second!
