Talk:NTFS reparse point

message: Can someone please give a source for this? I haven't seen anything - except MS's own products - that can set a reparse point for a file. Up to now I have only come across this for directories!

message: The text says:
: [NTFS reparse points] also can act as hard links, [...] they can point to directories on any local volume.
However, I have not found any evidence that hard links can point to folders. I have only seen them point to files, and I have not been able to create a hardlink to a folder.

replies: text:  Hardlinks cannot point to folders on NTFS, that's true. I think there is a sort of confusion here in that they can functionally act as hard links, but semantically they have little in common with hard links. --Assarbad (talk) 16:22, 12 December 2019 (UTC)

text: NTFS HARD link - since Windows NT4 - files on the same drive. DON'T USE.
I don't understand the DON'T USE comment at all.  This is a supported, documented feature of the operating system.  Just as with Unix hard links, the behavior of hard links with writable data is hard to predict, but that doesn't mean we should recommend not using them (we make sure we only use hard links with read-only data, which is a recommendation I would echo for Unix).  They're very hard for users to use, but we have systems that use this very widely in production with hundreds of people using both Samba and Window Server file servers.

replies: text:  For the side-by-side assembly (SxS) stuff Microsoft itself is using this. Hardlinks have already existed since at least NT 3.51. I have tested that myself since MoveFileEx() has always supported creating them (even though this was only semi-official). --Assarbad (talk) 16:22, 12 December 2019 (UTC)

text: NTFS HARD link – since Windows NT4 – files on the same drive...
It's not clear if this is on a physical disk or whether Hard Links can span a partition across multiple disks or even over a SAN or disparate mediums partitioned as one NTFS partition

replies: text:  "Same volume" would be the appropriate terminology. For most practical purposes a volume is identical with what is elsewhere called a partition. It's just that in some configurations a volume can span multiple physical disks. --Assarbad (talk) 16:22, 12 December 2019 (UTC)

message: I question if the DLT feature uses reparse points at all. Looks like little more than a GUID stored in the file metadata. No reparse points involved here.--Henke37 (talk) 00:55, 28 November 2020 (UTC)
