Apple File System (APFS) to replace HFS Plus, will work on all Apple devices

Apple has been working on a new proprietary file system for all its devices to replace the old HFS Plus. The new Apple File System (APFS) will be used by all Apple devices, which means that macOS, iOS, watchOS and tvOS will have a single file system to run on.

APFS didn't get any spotlight at this year's WWDC, but is nonetheless an important step toward a unified experience across wearables, mobile and desktop devices. Apple isn't all that keen on sharing a lot of details about APFS right now, but its developer portal offers some info for the curious:

APFS developer preview is available with macOS Sierra 10.12, with a final build aimed at a 2017 release. In its current state, the file system is still quite rough around the edges – which is to be expected from an early preview – in that it can't be used as a startup disk and doesn't run on Apple's proprietary hybrid Fusion Drives.

As for improvements over the current HFS Plus, Apple promises:

Beyond the aforementioned Flash/SSD storage optimizations, APFS is expected to add copy-on-write metadata, space sharing, cloning of files and directories, snapshots and fast directory sizing, among other features. APFS is scheduled for an official release in 2017.

All fancy new file system, yet still no central file management to take serious advantage of it on iDevices...

Probably saving that "innovation" for iOS 11...just like they implemented quick reply via banner notifications in iOS 9 or earlier (while device is unlocked), then they finally make it possible to do the same via the lockscreen in iOS 10, but restricted to 3D-touch-equipped devices :\

Is this to avoid paying royalties to Microsoft? That much more profit in the long run huh?

Microsoft Windows 10, and Surface scaring them into joining the party before they get left behind. They see the writing on the wall, and if they don't do this Windows will erode more of their sales. Good for them, now they can copy and sue MS and say that they invented this type of OS 1st. Once it is done ALL iFollowers will swear that Apple was the 1st do do it, and talk about how everyone is copying Apple's version. I am just loving the new IOS on screen messaging, and flexible display patent that they just invented here in 2016....rofl
