Content-Disposition to open an existing file?

[acidbox]

Is there a way, using the Content-Disposition header for file attachments, to open an already existing file on the client machine?

somthing like this in mind?

<?
header("Cache-control: private");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=c:\WINNT\system32\calc.exe");
?>

this wont work but is it kinda what your looking for?
