Well it seems every disk space analyser under the sun has been listed and the one with the most votes hasn't had a new release since the question was asked 7 years ago! For completeness let me add one of the newest and simplest that can quickly display which folders are using the most disk space and also export the list for printing. Folder Size Explorer also has the same familiar functionality as the built-in Windows Explorer so it's very intuitive.

I recommend Folder Size Explorer, one of the newest and simplest disk space analyzers that can quickly display which folders are using the most disk space and also export the list for printing. It has the same familiar functionality as the built-in Windows Explorer so it's very intuitive.
