Hi Dochelp, I am looking at MS-FSCC for the FileIdFullDirectoryInformation responses. The description of FileIndex is as: === FileIndex (4 bytes): A 32-bit unsigned integer that contains the byte offset of the file within the parent directory. For file systems in which the position of a file within the parent directory is not fixed and can be changed at any time to maintain sort order, this field SHOULD be set to 0 and MUST be ignored.<107> Footnote for <107> is : === <107> Section 2.4.18: When using NTFS, the position of a file within the parent directory is not fixed and can be changed at any time. Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 set this value to zero for files on NTFS file systems. Is this list of OSs where FileIndex == 0 for NTFS complete? I am testing against Windows2016 with a share on NTFS and it returns FileIndex==0 also. Can you check and clarify? regards ronnie sahlberg
