Set up PC folder backup
If you didn't see the prompt or you already closed the wizard, select the white or blue cloud icon in the Windows notification area, and then select Help & Settings > Settings, then Backup > Manage backup.
Access your backed-up folders on any device
When your files finish syncing to OneDrive, they're backed up and you can access them from anywhere in Documents, Desktop, or Pictures. When you back up your Desktop folder, the items on your desktop roam with you to your other PC desktops where you're running OneDrive.
If you're signed into the OneDrive sync app on your computer, you can use File Explorer to access your OneDrive. You can also use the OneDrive mobile app to access your folders on any device.
Change PC folder backup settings
If you want to stop or start backing up an important folder in OneDrive, you can update your folder selections in OneDrive Settings.
Important: When you stop backing up a folder, the files that were already backed up by OneDrive stay in OneDrive. If you no longer want those files in OneDrive, you'll need to move them to a local folder on your PC yourself. Any new files you add to that folder on your PC won't be backed up by OneDrive.
