How can I change the folder where the game puts the save games?

I installed Amnesia on the 'D' drive of my computer. However, the game created a folder in 'C/users/<account>/Amnesia/Main'. This was annoying, but it didn't really matter at the time, so I played the game.
But eventually, my 'C' drive ran completely out of room, so it wouldn't save anymore, so when I moved the 'Amnesia' folder into the 'D' drive, the game had no idea where to look for the folder, so it acted like I had never played it before, and there were no save games. So I was wondering if anyone had any idea how I could change the settings to make the game save games into the 'Amnesia' folder that's in the 'D' drive. Thanks!
