Thanks Henrik, but as the help for this function states:

Note
The components are separated by / (not \) on Windows.

, the slashes it uses are incorrect for use in a CMD window on a
Windows box (they need to be \ but file.path uses /). I suppose I can
do a query as to whether the platform is Windows (in which case use \)
or other (in which case use /) -- there isn't a more "clever" way of
doing this?
