Description[edit]
This clears the SaveData archive for the specified game, if the LowPath.Type is Empty then this will clear the SaveData for the current game. The target SaveData to format is determined by a Binary path, a game needs an exheader permission set in order to format the SaveData of another program.
See here for an example of how bucket counts should be calculated.
