.PARAMETER Folder
    The known folder to be read.
 .PARAMETER KnownFolder
    The known folder whose path is to be set.
 .PARAMETER Path
    The path to be set as the destination of KnownFolder.

“Can you truthfully say that you treasure something buried so deeply in a closet or drawer that you have forgotten its existence? If things had feelings, they would certainly not be happy. Free them from the prison to which you have relegated them. Help them leave that deserted isle to which you have exiled them” ~ Marie Kondo
