示例1: CalculateMaximumSize

        /**
         * Calculates the maximum size of a file which is addressable given the
         *  number of FAT (BAT) sectors specified. (We don't care if those BAT
         *  blocks come from the 109 in the header, or from header + XBATS, it
         *  won't affect the calculation)
         *  
         * The actual file size will be between [size of fatCount-1 blocks] and
         *   [size of fatCount blocks].
         *  For 512 byte block sizes, this means we may over-estimate by up to 65kb.
         *  For 4096 byte block sizes, this means we may over-estimate by up to 4mb
