The Feral Heart folder should be in your C: drive you get there by pressing the start button you know the one on the far bottom left if you're using a windows computer that is not a mac I'm not so sure if it's the same with macs
? Then you press "my computer"or "computer" then the C: drive or harddrive option on the next screen and from there you should easily see the Feral Heart folder. If not you may have to select a specific user profile under "users" then your log in name on the pc and then you'll find it
Hope that helps
