Transfer files between your iPad and computer with an external storage device
Connect your iPad or computer to an external storage device, such as a USB drive or SD card.
To connect to iPad, you may need a cable adapter. See Connect external storage devices to iPad.
The first time you connect the devices, select Trust when asked on iPad whether to trust this computer. (See the Apple Support article About the ‘Trust This Computer’ alert.)
Use a supported app like Files or Pages to copy files to the storage device.
For example, to copy a file from the Files app on iPad to the storage device, touch and hold the file, then tap Copy. Tap the name of the device (in the sidebar, below Locations). Select a location for the file, touch and hold the screen, then tap Paste. See Organize files and folders in Files on iPad.
Disconnect the storage device.
Connect the storage device to your other device, then copy the files to that device.
For example, to copy a file to your Mac, click the Finder icon in the Dock to open a Finder window, select the storage device (listed below Locations in the Finder sidebar), navigate to the file, then drag it to a folder on your Mac. See Connect and use other storage devices with Mac in the macOS User Guide.
