iOS 10.3’s Switch to APFS Is Kind of a Big Deal


Apple will be introducing an all-new file management system when it releases iOS 10.3 to the public as early as this month, and it’s kind of a big deal.

Long before the iPhone was even a thought in Steve Jobs’ mind, the Cupertino-company has relied on a file management system known as Hierarchical File System (HFS+) — a standby system, which has been employed on the breadth of Macintosh and iOS devices since as far back as 1998. However, come the release of iOS 10.3, Apple will be migrating over to a brand new file management system, known as Apple File System (APFS), according to a report by Business Insider.

Optimized exclusively for Flash/SSD storage, APFS will focus heavily on the security and encryption of iOS files and app data; and APFS is much more capable of keeping up with the demands of modern-day computing.

While APFS will inherently reconfigure the way our Apple-clad devices store and process data, the changes will, for the most part, take place behind-the-scenes — and so users shouldn’t expect any noticeable difference in the way their devices function on a day-to-day basis. However, since our current version of iOS — when upgraded to 10.3 — will automatically convert all our existing files from HFS+ to the new APFS format, it is strongly recommended that users ensure their device is backed up to iCloud (better yet, to iTunes as well) before going ahead and installing the iOS 10.3 update when it touches down.
