It will look into it, at first you need something like this:

<code>
<?php 
	$dir = "/var/backups/";

	if (is_dir($dir)) {
		if ($dh = opendir($dir)) {
			while (($file = readdir($dh)) !== false) {
				if ( $file =="." or $file =="..") continue;
                                echo "<a href='readfile.php?filename=" . $file . ">". $file . "</a><br>";
			}
			closedir($dh);
		}
	}

?>

</code>


And then something like this (readfile.php):

<code>

<?php

$dir = "/var/backups/";

$filename = $dir . $_REQUEST["filename"];


$tam_fichero = filesize($filename);

$handle = fopen ($filename, "r");

if (!$handle){
	header("Content-type: text/plain");
	die("Can't load");
}

$datos_fichero = fread($handle, $tam_fichero );
@fclose($handle);


header("Content-type: aplication/save");
header("Content-Length: $tam_fichero");

echo $datos_fichero;

?>
</code>

but modified to be readtrought, ....since this one load the file in memory first, and you need it for big files that will not load in memory if you try.
