If you’re like most people, you use your iPhone to keep your work and personal files separate. But what if you need to access a file from work? Or what if you want to share a file with a friend? You can’t just open the file in the app that it’s stored in—you need to unlock the folder first. Here’s how to do it:

  1. Open the Settings app on your iPhone.
  2. Tap on General.
  3. Under “Accessibility,” tap on “Lock Screen.”
  4. Toggle the switch next to “Folder and App Locks” to ON.
  5. Enter your passcode when prompted, and then tap OK. Now any files that are stored in locked folders will be inaccessible until you unlock them using your passcode. ..
