In this video below, I show tips for setting up a new SD card with the Microsoft Surface. I show how to move your OneDrive folder to the MicroSD card, how to move Windows 10 Apps to the card, and also how to change your other media folders. This video applies to all Surface devices running Windows 10, including the Surface Pro 4, Surface Pro 3, and Surface 3.
