Apple says they intend to open-source the file system in the docs. Open Source : "An open source implementation is not available at this time. Apple plans to document and publish the APFS volume format when Apple File System is released in 2017."
Free software and patent-free or whatever some lawyers call "open"?

Re: Apple File System
#43Just saw a comment in another thread, stating Apple had slipped in improving their Unix layer, and here comes this. New file system is not a joking matter: Microsoft failed to deliver their new FS; Linux took years to go from ext2 to ext3 to ext4, and btrfs is in forever testing; most of *BSD still use their old ones; zfs took decade to become mainstream... The information currently is very scarce on this one, but I…

Didn't Microsoft introduce ReFS with many modern FS features?

Basically, ZFS datasets.

If those can be sent: Finally Time Machine done right.

Interesting.

Yay!
Limitations: https://developer.apple.com/library/prerelease/content/docum...
Edit:
> encryption models for each volume in a container: no encryption, single-key encryption, or multi-key encryption with per-file keys for file data and a separate key for sensitive metadata
Nice. I hope they also include checksums for each block.
Famously missing, but not the hardest thing to add considering all the features above: Compression (which HFS+ supports!)

#46> It is optimized for Flash/SSD storage and features strong encryption, copy-on-write metadata, space sharing, cloning for files and directories, snapshots, fast directory sizing, atomic safe-save primitives, and improved file system fundamentals. \o/ Hallelujah, something modern!

#47Earlier quoted context omitted.
I was excited to until I read the limitations section. Can't be used as the startup disk and doesn't work with time machine. Hopefully this with change in the next macOs release.
Sure, this is a developer preview. Final release in 2017 will surely make this FS the default.

Re: Apple File System
#50Siracusa will finally be happy. ;-) Sounds an awful like like ZFS (zero-cost clones, read-only snapshots) but could it be? I would imagine they'd start from scratch to due IP issues. Clearly this is immature technology they want to get out for testing/evaluation before it's fully adopted even into their own products. (See below.) - - - from the release notes - - - As a developer preview of this technology, there are…
This one is confusing, because this is a logical volume feature. Not sure how or why APFS would ever care that some layer above it is encrypting stuff.
