Windows 10: How to add specific folders to "Backup - File History"?

I can't backup any specific folders in my Documents folder unless the Documents folder itself is backed up. Otherwise trying to add them does nothing. Adding the Documents folder to the backup list causes my other folders to appear on the list.


Why is this? Am I expected to exclude my 15 other folders? What if I had 150?

Backup These Folders in File History

My Pictures and My Videos folders are inside the My Documents folder. In File History all three folders are listed in the Backup These Folders list. Does this mean that because of this, files in Pictures and Videos are backuped twice? Once when backing up
My Documents and once when backing up My Pictures and My Videos (included in My Documents)

 

How to remove folders from File History

• I had the same problem, and I solved in this way:
  Control Panel -> System and Security-> File History -> Turn off
  Settings -> Update & Security -> Backup -> More options -> Stop using this drive
  Delete the File History folder in your external drive.
  Start using File History again.
  After performing these steps, I can easily add folders to "Excluded Folders" and they remain excluded. I checked in the actual files and folders saved on the external disk, and it works.
  I did not modify the default settings about how often and how long backup is saved, File History is working ok now. So I guess it is important to click "Stop using this drive" in order to reset File History.
  Hope this will be helpful
