>Anybody remember XTREEPRO... it could analyse your complete disk and then sort by size...across directories. Is there anything similar in Windows .

I remember that one. We used that as our primary tool when I worked at the University. I believe we stopped using it when they released a Windows version. Or, did they? I'm not sure about that one but many vendors stopped doing utilities like that when people all migrated to Windows because of its built in tools such as the Windows Explorer.
