What is the best tool for visualising hard drive usage on Windows Server 2008 (Web Edition)?

I've recently been tasked with cleaning up our Windows Server 2008 (Web Edition) server's website data folder.

There are over 50 sites hosted on this particular box, so I'm looking for an easy way to scan the the data folder, along each child folder to determine where the MB hogs are hiding.

On my development machine I use WinDirStat, but I'm not sure that this would be the best solution on a production server?

How would you go about it?

Have a look at Treesize Free.

I use WinDirStat on my production SharePoint server (not to mention any other computer where I wonder what is eating up my hard drive space). I love it and wouldn't use anything else.

The old version of SpaceMonger (this one) is free, doesn't need to be installed and gives a nice graphical overview. But I don't know if it'll work on Windows Server 2008.

Hope this helps.

I use Total Commander file manager. Simply press Alt+Enter and you see dir sizes. It is very convenient for such tasks.
