        // Get value of text box
        var text = jQuery(this).val();
        
        // Set value of file box (produces error)
        jQuery('input[type=file]').val(text);
    
    });

});

The reason for the above should be fairly obvious, imagine let's say that the file input value WAS settable via JavaScript ( or any other method for that matter ) important confidential files could be set silently by just having several file inputs on the page upon load hidden via css. Press Submit, the next page takes a while to load but you just attribute it to a laggy connection. Meanwhile, the fiends are absconding with your precious files.
