How do I transfer files to another device?
+ +Files can be transferred to another device using an external drive, USB + file transfer via MTP / PTP or an app-based mechanism.
+ +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.
+ +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).
