FileReferenceNumber (8 bytes): A 64-bit unsigned integer that contains the file reference number for the file. NTFS generates this number and assigns it to the file automatically when the file is created. The file reference number is unique within the volume on which the file exists.

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.
