One of the biggest changes in
Windows 8.1 is SkyDrive integration. In Windows 8, SkyDrive was available as a Modern app and a desktop app that you could install. In Windows 8.1, SkyDrive is integrated at the system level.
SkyDrive integration doesn’t just apply to Modern apps. It’s also available in File Explorer on the desktop, so this change matters to desktop users, too. SkyDrive’s File Explorer integration works a little differently from Dropbox and other cloud storage apps.
This also works with
Windows RT, so Surface RT users finally have a way to sync SkyDrive files to their local storage and access them from the desktop.
