and also you can get Human Disk Free Space result in GB in This Example :

<?

function dfs_gb($drive)

{

        if($drive)

        {

        return round(diskfreespace("$drive:")/1024/1024/1024,2); //To Get Human Result in GB we divid it By 1024 Byte & 1024 KiloByte & 1024 MegaByte

        }

}



echo dfs_gb(D); //(D) is a drive letter

?>
