Using The Smart Files Feature

Smart Files is a new feature in Windows 8.1 that allows you to view your SkyDrive files without having to download everything onto your computer. When you browse through your SkyDrive folder in File Explorer, you'll see a column called 'Availability'. By default, all the files are listed as Online-only, which means that as long as you are connected to the Internet, you can view the files without actually having them on your computer's hard drive. If you want a particular SkyDrive file or folder to be available offline, just right-click on it and select the 'Make available offline' option.
