FileReferenceNumber (8 bytes): The 64-bit file ID, as specified in section 2.1.9, for the file. For file systems that do not support a 64-bit file ID, this field MUST be set to 0, and MUST be ignored.

ObjectId (16 bytes):  A 16-byte GUID that uniquely identifies the file or directory within the volume on which it resides. Specifically, the same object ID can be assigned to another file or directory on a different volume, but it MUST NOT be assigned to another file or directory on the same volume.

ExtendedInfo (48 bytes):  A 48-byte BLOB that contains application-specific extended information on the file object. If no extended information has been written for this file, the server MUST return 48 bytes of 0x00 in this field.
