Помогите с добавлением документа на HD. У меня есть готовое дерево которое описывает структуру каталога. Мне необходимо при нажатию на кнопку, добавлять новый документ в дерево каталогов (оно загружается в левый фрейм) а также в этой папке создавать новую ссылку на нужный документ на диске (для упрощения новая папка уже скопирована в корневой каталог). На Java script статическая структура дерева организована. Заранее благодарю. Вот примерный код:
<HTML>
<HEAD>
<link rel="stylesheet" href="style.css" type="text/css">
<meta http-equiv="content-type" content="text/html; charset=windows-1251">
<title>Материалы к ИИ</title>
<script language="JavaScript">
<!--
function thetext(txt) {
document.theform.thetext.value = txt
return true;
}
//-->
</script><script language="JavaScript"><!--
function atext(txt) {
document.aform.atext.value = txt
return true;
}
//--></script>
<script LANGUAGE="JavaScript">

// node[0] is 0/1 when the node is closed/open
