+                    <p>Files can be transferred to another device using an external drive, USB
+                    file transfer via MTP / PTP or an app-based mechanism.</p>
+
+                    <p>To use an external drive, plug it into the phone and use the system file
+                    manager to copy files to and from it. The only difference on GrapheneOS is USB
+                    peripherals such as USB flash drives will be ignored unless they're plugged in
+                    at boot or when the device is unlocked. You can configure this in Settings ➔
+                    Security.</p>
+
+                    <p>Transferring files to an attached computer is done with MTP / PTP. After
+                    plugging in the phone to the computer, there will be a notification showing
+                    the current USB mode with charging as the default. Pressing the notification
+                    acts as a shortcut to Settings ➔ Connected devices ➔ USB. You can enable file
+                    transfer (MTP) or PTP with this menu. It will provide read/write access to the
+                    entire profile home directory, i.e. the top-level directory named after the
+                    device in the system file manager. Due to needing to trust the computer with
+                    coarse-grained access, we recommend transferring files with a flash drive or
+                    an app with end-to-end encryption such sending the files to yourself via an
+                    end-to-end encrypted messaging app like Element (Matrix).</p>
