CopyFiles behavior

I have the following line in my .nsi file

CopyFiles "$EXEDIR\ARDAT" "$OUTDIR"

And I thought that it would take all the files and directories in the $EXEDIR\ARDAT directory and place them directly into the
$OUTDIR directory.

Instead, it places all the files into $OUTDIR\ARDAT

Why is that? How do I NOT make it do that?

Thanks

Try "$EXEDIR\ARDAT\*.*"

Cool, it worked great! Thanks a lot.
