Apple’s New Filesystem and Why it Matters to You

In March, Apple began rolling out a new filesystem named, appropriately enough, the Apple File System (APFS).

It is a replacement for the existing HFS+ filesystem which Apple has used since 1998 for its devices. If you are an Apple user, as you upgrade to iOS 10.3, tvOS 10.2, watchOS 3.2, or MacOS High Sierra (coming this Fall), your device will be automatically updated to the new APFS.
