input type= file problems

	I want to use this:

<SCRIPT LANGUAGE="JavaScript">
<!--
	function validar() {
		document.formulario.texto.value = "mi texto";
		document.formulario.FILE1.value = "c:\rascacielos.jpg";
	}


//-->
</SCRIPT>

     inside a web page like this:

<form action="http://www.pppp.es/cgi_upload/upload.cgi" method="post"
name="formulario" enctype="multipart/form-data">

<input type="File" name="FILE1" >
<p>
<input type="Submit" value="submit">
<p>
<input type="button" value="cargar" onClick="validar()">
