    #   path processing. Thus relative paths are not resolved and slash is not
    #   translated to backslash. It has the native NT path limit of 32767
    #   characters, but a bit less after resolving device symbolic links,
    #   such as '\??\C:' => '\Device\HarddiskVolume2'.
    # * '\\?\c:/a' looks for a device named 'C:/a' because slash is a
    #   regular name character in the object namespace.
    # * '\\?\c:\foo/bar' is invalid because '/' is illegal in NT filesystems.
    #   The only path separator at the filesystem level is backslash.
    # * '//?/c:\a' and '//?/c:/a' are effectively equivalent to '\\.\c:\a' and
    #   thus limited to MAX_PATH.
    # * Prior to Windows 8, ANSI API bytes paths are limited to MAX_PATH,
    #   even with the '\\?\' prefix.
