Space Army

Hi does anybody know how to mod engine trust/fuel/mass??

How can I load a .craft file if i can't even find the game folder in the Computer menus??? I downloaded the game 2 weeks ago and at that time i could see the folder but now there's just the Application icon. The game still loads even though there isn't the folder. Has it got something to do with opening the game folder in WIN.rar ??? Thanks for your help.
