copy the folder to the corresponding save folder on your computer. you must rename that folder to the same format as your save files (i.e. 000002 - Game1). You don't need to rename it to the correct number so long as the format is preserved. Click on load game and find the file - the number is likely to be different, and may belong to either character (there are two of them).  An easy way to resolve this is to move all of the folders in at once and rename them one at a time. The rest of the folders that do not follow the format will be named as "Quicksave" in the load screen. The achievement list is described below as such : (achievement - folder name)
