Similarly, you can also use Microsoft OneDrive to sync your files between a mobile and the desktop with just a few taps. OneDrive is Microsoft's official online storage that's used by default on Windows computers. You can download the OneDrive app on your Android phone to seamlessly share, back up, and even view files between the two devices. You get 5GB of free cloud storage on OneDrive, but you can always upgrade your account to add more space.
