Can I (pre)set the value of a INPUT TYPE="file" element?

Martin Honnen,

With NN4 and NN6 you can (pre)set the value of an
  <INPUT TYPE="file">
element, but only with trusted script:
  <FORM NAME="aForm"
        METHOD="post"
        ENCTYPE="multipart/form-data"
        ACTION="yourUploadHandler"
  >
  <INPUT TYPE="file" NAME="aFile">
  <INPUT TYPE="submit" VALUE="send us your registry">
  </FORM>
  <SCRIPT>
  if (window.netscape) {
    netscape.security.PrivilegeManager.enablePrivilege
('UniversalFileRead');
  }
  document.aForm.aFile.value = 'C:\\WINDOWS\\System.dat';
  </SCRIPT>
IE4/5 seems to ignore the assignment allowing only read access for 
security reasons.
