вот, я нашел этот скрипт в инете но не работает
<html>
<body>
<script language="JScript">
<!--
function getCount(foldername)
{
var myObject, f, filesCount;
myObject = new ActiveXObject("Scripting.FileSystemObject");
f = myObject.GetFolder(foldername);
filesCount = f.files.Count;
document.write("The number of files in this folder is: " + filesCount);
}
-->
</script>
<form name="myForm">
Enter the name of a folder which contains files.
<input type="text" size="35" name="file">
<br><br>
<input type="Button" value="Get File Count"
onClick='getCount(document.form1.file.value)'>
</form>
