  21 /* At least since Windows 2000 it's possible to add FolderShortcut objects
  22  * by creating some registry entries. Those objects, which refer to some
  23  * point in the filesystem, can be registered in the shell namespace like other
  24  * shell namespace extensions. Icons, names and filesystem location can be
  25  * configured. This is documented at http://www.virtualplastic.net/html/ui_shell.html
  26  * You can also google for a tool called "ShellObjectEditor" by "Tropical
  27  * Technologies". This mechanism would be cool for wine, since we could
  28  * map GNOME's virtual devices to FolderShortcuts and have them appear in the
  29  * file dialogs. These unit tests are meant to document how this mechanism
  30  * works on windows.
  31  *
  32  * Search MSDN for "Creating Shell Extensions with Shell Instance Objects" for
  33  * more documentation.*/
