How do I set up external storage?

When you connect a compatible external storage drive, Xbox One will walk you through setting it up to store games and apps.

The basic requirements for storing games and apps on an external drive are:

Has capacity of 256 GB or more
Uses USB 3.0.

Devices that don’t meet the above requirements will be treated as media storage, such as for music or video. If you have a storage device that does meet the above requirements for game and app storage, you can cancel the format to use it as a media device.
How do I manage external storage?

In My games & apps, you can view content by storage device. To do this, highlight a game or app, press the Menu button on your controller, and then select Manage game. You will then be able to move or copy content between storage devices.
