[Windows Explorer Switches]
 Windows Explorer switches are useful in creating rooted folders:
      Explorer [/e][,/root,<object>][[,/select],<sub object>]
 /e
    Use Explorer view (scope and results pane view). The default is
    Open view (results in pane view only).
 /root<object>
    Specify the object in the "normal" name space that is
    used as the root (top level) of this Explorer/Folder (i.e., local
    path or UNC name). The default is the Desktop).
 /Select
    The parent folder opens and the specified object is selected.
    <sub object>   Specify the folder unless /select is used. The
    default is the root.
