The Files app was introduced in iOS 11 as a replacement to iCloud Drive app. It allows you to browse, search, and organize all your files stored on your device, in iCloud Drive or in other supported third-party apps, like Google Drive or Dropbox. You can organize your files by Name, Date or Tags, but first lets look at how to add third-party apps so all your files will be displayed.
One of the great features of iOS 11 and later is the Files app. Saving and browsing files directly on an iPhone, iPad or iPod touch now has native support. Not only can files be stored locally on the device, but iOS can take advantage of cloud-based storage solutions such as iCloud or Dropbox. Individual apps can even be configured to use different locations for file storage by default.
