OneDrive is Microsoft's service for hosting files in the "cloud", that's available for free to owners of a Microsoft account. OneDrive offers users a simple way to store, sync and share all kinds of files, with other people and devices on the Web. Xbox One, Windows 8.1, Windows 10 and Windows Phone use OneDrive also for synchronizing your system settings, visual customizations, themes, app settings and even Internet Explorer or Microsoft Edge tabs, history and saved passwords.

The files stored in OneDrive can be accessed directly from a web browser or, if you're using Windows 8.1 or Windows 10, directly from the operating system. Other means of accessing your OneDrive files include apps for Windows, Windows Phone, Xbox and even Mac OS X, iOS or Android. These apps can be downloaded from the official OneDrive website.

OneDrive for Business and Office 365 make it easy to manage your work files, share them, and collaborate with others from any device.

Getting started with OneDrive for Business is easy. You can add files already on your PC to OneDrive by either copying them over or moving them from your PC. When you save new files, you can choose to save them to OneDrive so you can get to them from any device and share them with other people. And, if your PC has a built-in camera, you can automatically save copies of the photos in your camera roll to OneDrive, so you'll always have a backup.
