Hi Doug, that folder is created by 3D Builder
In order to delete that folder you will need to uninstall 3D Builder, if you do not use it
Right click your Start Button, choose Powershell (admin)
Paste this command into Powershell and hit Enter:
Get-AppxPackage *3dbuilder* | Remove-AppxPackage
Close Powershell
That folder should now be gone . . .
