Apple has released iOS 10.3 update for iPhone, iPad and iPod Touch. In all these years this is the first time Apple is changing the file system. This is certainly a big step where the file system is changed from HFS+ to Apple File System. The Apple File System is up with various improved features which consist of the encryption system, a much-improved file time stamping, along with it better storage system. Though the current version is equipped with the beta testers, so there is nothing to worry.
