There's a little thing that I can't totally understand: why on Microsoft's PartnerSource site (the Microsoft Partner's reserved area) if you want to download a file (product releases, service packs, hotfixes etc.) you have to install the Microsoft File Transfer Manager ActiveX control?

Is it really necessary? Ok, it's not a big work to install it (it's very light), but it's a control that is used only in this area so... why????
