Folder size

Is there a way to display folder sizes on win2k? I have several folders, some are user’s folders and some not in various directories on my server. I should not be as low on space as I am and I want to find the folder(s) that are eating up the space and move them or delete information from them, but I don’t want to right click each and every one and choose properties. I want to query a group of folders for their sizes.

Thanks,
Monte
