filetype() does not work for files >=2GB on x86 Linux. You can use stat as a workarround:$type=trim(`stat -c%F $file`);Note that stat returns diffenerent strings ("regular file","directory",...)

I use the CLI version of PHP on Windows Vista.  Here's how to determine if a file is marked "hidden" by NTFS:<?phpfunction is_hidden_file($fn) {    $attr = trim(exec('FOR %A IN ("'.$fn.'") DO @ECHO %~aA'));    if($attr[3] === 'h')        return true;    return false;}?>Changing <?php if($attr[3] === 'h') ?> to <?php if($attr[4] === 's') ?> will check for system files.This should work on any Windows OS that provides DOS shell commands.
