Distribution Download

[romeu]

I want to download the entire distribution of linux from ftp.debian.org.
What (windows) program should I use for this purpose? I mean, I want to
select the directory ftp.debian.org/debian and download it all with just
one click. I tried CuteFtp, but it does not deal good with proxies
authentication (oh, I'm at work, so I'm using Windows, behind a firewall).
