Talk:HFS Plus

Arbitrary section break

Isn't the official name of the file system HFS+, not HFS Plus? — Preceding unsigned comment added by 68.0.211.71 (talk • contribs) 01:58, September 21, 2004 (UTC)

Apple use both names interchangeably: http://developer.apple.com/technotes/tn/tn1150.html AlistairMcMillan 08:34, 21 Sep 2004 (UTC)

Doubting -most- other file systems do not support hard links.

I added a dubious tag to the claim that most filesystems beside HFS+ does not support hard links. Besides the FAT systems and some ancient ones that are no longer used (I have no idea how many that amount to), I don't know of any formats that does not support hard links. The claim is unsupported by any sources and I doubt any will ever be made. — Preceding unsigned comment added by 89.239.195.102 (talk) 05:18, 9 June 2022 (UTC)

That's not the claim being made; the claim is that, unlike most file systems, HFS+ supports hard links to directories. No claim is made about supporting hard links to plain files.

I changed it to say that, unlike most file systems that support hard links, HFS+ supports hard links to directories. Hopefully that makes it clearer what the claim is.

Note that this is a consequence of the code that implements the file system; the support for hard links to directories was added for Time Machine - Time Machine backups to HFS+ all have complete file system directory trees, not just partial trees of files modified since the last backup, but save space by hard-linking to unchanged files and unchanged directories, where "unchanged", for directories, means "the directory has the exact same set of files and subdirectories and all of those files and directories are unchanged as well".

"Sequoia" reused for macOS 15

Shouldn't be added to the article, but I think that's pretty interesting, especially considering it doesn't even use HFS+. It uses APFS (like 10.14+). 104.63.56.194 (talk) 01:50, 14 April 2025 (UTC)

Companies may use codenames without there being any significance to the reuse. It's not as if macOS Sequoia was the first version of macOS to default to APFS, nor has Sequoia, as far as I know, dropped support for HFS+ file systems (given that people probably have HFS+ volumes on external hard drives/SSDs, and that some of those may be Time Machine backups, which might not be convertible from HFS+ TM drives to APFS TM drives, there may be an incentive for Apple to continue to support HFS+).

It's of some interest, but I don't know that it's of significant interest. Guy Harris (talk) 05:59, 14 April 2025 (UTC)

(The IABot's sending these notices out again?) Thanks for noting that the Mediafour site isn't working; maybe they got bought by Other World Computing, or maybe they were always part of OWC, but the Mediafour brand appears to be dead, and the MacDrive site is now at https://macdrive.com - and they no longer support HFS, but they do support APFS. I've updated the page appropriately. Guy Harris (talk) 06:20, 10 September 2025 (UTC)
