If you did google it, and could not find a good option then you clearly are more hopeless then I expected. Why you are being so hostile is beyond me. By the way, its "Software" not "softwear" Get better at googling, I understand that some people learn slower than others so I shouldn't expect you to know how to google. But @CryptoMatt showed you how to google this topic, and it very clearly showed windirstat under the first result take note of what he typed into google. Also, notice he wrote more of a question seeking an answer then misleading post with a very poor description titled "Need Software". I would also say your original post has a lot of grammatical errors that no one corrected you on so please don't correct other people errors. Good day.
