    # Interesting findings about extended paths:
    # * &#039;\\?\c:\a&#039; is an extended path, which bypasses normal Windows API
    #   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 &#039;\??\C:&#039; =&gt; &#039;\Device\HarddiskVolume2&#039;.
    # * &#039;\\?\c:/a&#039; looks for a device named &#039;C:/a&#039; because slash is a
    #   regular name character in the object namespace.
    # * &#039;\\?\c:\foo/bar&#039; is invalid because &#039;/&#039; is illegal in NT filesystems.
    #   The only path separator at the filesystem level is backslash.
    # * &#039;//?/c:\a&#039; and &#039;//?/c:/a&#039; are effectively equivalent to &#039;\\.\c:\a&#039; and
    #   thus limited to MAX_PATH.
    # * Prior to Windows 8, ANSI API bytes paths are limited to MAX_PATH,
    #   even with the &#039;\\?\&#039; prefix.
