I have modify my folder.php in sapphire/filesystem/Folder
to be able to get the size of a folder directly with a folder object, I have ovverrides the function getAbsoluteSize of file

this is called reccursivily ion case of folder inside the folder..

//return the size in octet
   public function getAbsoluteSize($path='')
   {
   
      if(empty($path))
      {
         $path = Director::baseFolder() . '/' . $this->getRelativePath();
      }
      $h = @opendir($path);
      
      if($h==0)return 0;
      $sf = 0;
      
      while ($f = readdir($h))
      {
         if ( $f!= "..")
         {
            $nd = $path ."/". $f ;      
            if( $f!=".")
               $sf += filesize( $nd );
            if( $f!="." && is_dir($nd))
            {
               $nd = $path . $f ;
               $sf+= $this->getAbsoluteSize( $nd );
               
            }
         }
      }
      closedir($h);
      return $sf ;
   }

For information, you can do it also with a shell but this requires 751 CHmod on the folder (more access..less security)

$folder = "home/tea/mail/";

if($pass === "eggnut") {
$job = shell_exec("du -s -k $folder"); //summary
echo "<b>SIZE in KB:</b> $job";

I do not like to change my core, for the further versionning.
But I do not need another class folder, and actually $Myfolder->getAbsoluteSize() exist and does not give the good result.

If a guy of the core dev read this post do you think,; it culd be a good think to integreta this to the further versions.
Thanks.

Your framework is awesome guys !
