What is OneDrive? 
OneDrive is the place to store and share your documents in the cloud. All content you store in OneDrive is private until you decide to share it with other people. View and edit Office documents in Office Online or open them for viewing or editing in their Office applications. Use OneDrive in your web browser or sync it to your computer to access content locally and when you're offline. Access your OneDrive content on all your favorite devices, including Windows Phone, Surface RT, Windows 8, and iPhone or iPad.
