How so? The whole idea is that the underlaying OS that handles the
copying should also know to copy everything, otherwise you can
implement everything into applications and just skip the whole
filesystem part.

Of course, it won't work if applications themselves are actually
transferring the data and create the new files directly onto the
filesystem. This just seem so wrong.
