According to the specification v.3.3.0, Chapter 7.18, Table 74, the Size row: > If the size is 32 GB-1 MB or greater, the > field value is 7FFFh and the actual size is stored in > the Extended Size field. Therefore the Extended Size should replace the value of Size if the latter equals 0x7FFF. The Extended Size should not be added to Size. Also, since Extended Size is DWORD, Size should not be ushort.
