Question Get folder size from web server

[arjan]

Hello,

I've been searching for hours without success I hope you can help me out.

I want to download a specific folder form my web server. I have the script to download the files from that folder and it's working, but I now want to get the total folder size so that I can make an progressbar.

Does anybody know how to get the total folder size from an web server?
(for example www.yourdomain.com/items )

Thank!

Arjan
