I need to reinstall windows and don't want to lose my progress, but I can't find the save games. All searching has pointed me to an Almost Human folder, but I don't have an Almost Human folder anywhere (that I can find) so I think that might be for the first game? Where are the saves? I bought the game from GOG, if that makes a difference. Can anyone help?

The path is: In windows explorer click on Documents and the AH folder is there:

My game was from Humble Bundle.

Thank you!
