How much space do I have on my Surface?

To see how much drive space you have on your Surface:

The amounts of available free space and total available space are shown. If you're running low on space, the drive will be marked in red.
Check available storage in This PC

OneDrive: Cloud storage

OneDrive is free cloud storage that comes with your Microsoft account. It’s like an extra hard drive that’s available from all your devices. For info on using OneDrive, see Using OneDrive on Surface.

Note: OneDrive syncs files from the cloud to your Surface. Syncing or sending data across a mobile broadband connection could result in extra charges. For more info, see Manage your mobile broadband data usage.

Removable storage options

You can use USB storage or a microSD card of any size with your Surface to store your documents, music, videos, and pictures. Surface works with standard microSD card formats—microSD, microSDHC, and microSDXC. If you have a Surface Book, you can also use a full-size SD card.
