If I ignore your claim that the posted code copies a directory,
i.e. assume that nothing clever is going on, then everything gets much
less unlikely*. You probably just want to use

  file:open(Src, [binary, read, raw])

and

  file:open(Dest, [binary, write, raw])call, with the options [raw,

   work on linux. It probably hasn't worked on any unix for about 15
   years.
