The prefix - // indicates to the NT object manager to lookup the object relative to "\Sessions\0\DosDevices\[Logon Authentication ID]". - // - // There is also a special "\Global??\" prefix that refers to the system logon. User's session directory shadows - // the system logon directory, so that when the referenced object is not found in the user's namespace, - // system logon is looked up instead. - // - // There is a symlink "Global" in the user's session namespace that refers to the global namespace, so "\??\Global" - // effectively resolves to "\Global??". This allows Win32 applications to directly refer to the system objects, - // even if shadowed by the current user's logon object. - // - // NT paths can be used to reference not only local filesystems, but also devices and remote shares identifiable via - // UNC paths. For this, there is a special "UNC" device (which is a symlink to "\Device\Mup") in the system logon - // namespace, so "\??\UNC\host\share" (or "\??\Global\UNC\host\share", or "\Global??\UNC\host\share") is equivalent - // to "\\host\share". - // - // NT paths are not universally accepted by Win32 applications and APIs.
