That's right; say goodbye to deleting photos at the last moment or wondering why you bought a 16GB iPhone. Instead, you might see a lot of storage open up on your phone. What magic is making this possible? iOS 10.3 includes a new file system format, called Apple File System (APFS), which is replacing the 31-year-old Hierarchical File System (HFS). APFS might bring a slew of new features to the iPhone in the future. For now, however, it's just freeing up more space on your phone.
Plenty of people, as you can imagine, are excited about the change.
Wow, iOS 10.3 gave me 3 gigs of storage #ios103

Before you start downloading iOS 10.3, don't forget to back up your phone and all your important files.
