Sync files with OneDrive in Windows
Sync files with OneDrive in Windows (microsoft.com)
With OneDrive, you can sync files between your computer and the cloud, so you can get to your files from anywhere - your computer, your mobile device, and even through the OneDrive website at OneDrive.com. 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.
This article describes how to download the OneDrive sync app and sign in with your personal account, or work or school account, to get started syncing.
