Please bear in mind, these are not your save games or the same folder which contains these, this folder is completely unrelated. Upon deleting your preferences the in-game preference settings will be restored to default, so the folder will be regenerated when you launch the game.
The next time you launch the game remember to change any preferences you wish to have changed (such as auto save regularity, sound level or game display mode).
