FTP folder size

Hi everyone. I have the following (fairly simple) feature request: the ability to get the total size occupied by the online/FTP folder.

I was surprised I couldn't find this function, maybe I overlooked it...

I know, but that's not always possible (no scripting support) or needed (to calculate the size of relativly few folders).

I also agree that it's kind of trivial. But it would make smartFTP just another bit more complete.
