onedrive忽略子文件夹

Select the white or blue OneDrive cloud icon in the Windows taskbar notification area.
In the activity center, select More > Settings.

Select the Account tab, and select Choose folders.

Note: You might need to select the Show hidden icons arrow The Show hidden icons button. next to the notification area to see the OneDrive icon.          

I tried that previously, but that doesn't necessarily solve my problem.

All that does is make that folder inaccessible on my laptop, but keeps it in OneDrive.

I want the opposite, kept on my laptop but not synced to OneDrive.
