If it were possible, the following would do it. However on Netscape Navigator 4 on Linux this generates the error: "Warning: Cannot find callback list in XtCallCallbacks":

<form name="myForm">
<input type="file" name="myFile">
</form>

<script language="JavaScript"><!--
if (document.myForm.myFile.click) {
  document.myForm.myFile.click();
}
//--></script>
