Deleting the Persistent Storage

  1. Start Tails from the USB stick on which you want to delete the Persistent Storage.

  2. In the Welcome Screen, keep the Persistent Storage locked.

  3. Choose Apps ▸ Tails ▸ Persistent Storage.

  4. Click Delete in the right of the title bar.

This technique might not prevent a strong attacker from recovering files from an old Persistent Storage using advanced data recovery techniques, especially if the Persistent Storage had a weak passphrase.
