Overview of Apple File System (APFS)

APFS, short for Apple File System, is a new file storage system for macOS, iOS, watchOS, tvOS, and Apple devices. Compare to the 30-year-old HFS+HFS+, APFS has many new features and benefits, such as improved storage, faster performance, enhanced data integrity, and encryption, etc. Once macOS 10.13 was released, Apple made APFS available to every Mac computer, iPhone and iPad owner, eventually APFS replaced HFS+. When and if you upgrade your system to macOS 10.13 High Sierra, 10.14 Mojave, or 10.15 Catalina, the system drive will be automatically converted HFS+ to APFS.

If you upgrade to macOS 10.13 High Sierra, 10.14 Mojave, or 10.15 Catalina, you might have spent some time experimenting with APFS (Apple File Stem).
