With OneDrive for Business, you can sync files between your computer and the cloud, so you can get to your files from anywhere - your computer, your mobile device, or a web browser. If you add, change, or delete a file or folder in your OneDrive folder, the file or folder is added, changed, or deleted on the OneDrive website and vice versa. You can work with your synced files directly in File Explorer and access your files even when you’re offline. Whenever you’re online, any changes that you or others make will sync automatically.
