If you find yourself running out of room on your Xbox One console, you can plug in an external hard drive to instantly give the system a bit more breathing room, provided it's USB 3.0 compatible, has a partition created on it, and is larger than 256GB in size. In fact, you can connect up two hard drives at the same time, if you need a lot of extra space.
If you connect a suitable drive, the Xbox One should automatically take over and guide you through the process of getting it set up. Go to 'System' then 'Storage' from the 'All Settings' page to customize and configure the attached storage further.
