I gave it a try today and I saw a lot of duplication. I'm on Windows-7, so the Users directory and the Documents and Settings directory are the same. I also have some links created via mklink that link to network drives. It counted those in my total, so I only have a 128G disk, the total was much higher. See image.

This is probably solved in vers 1.4.2, just released :)
Yes! I upgraded today to 188.8.131.52 and all the problems mentioned were fixed. Awesome. Thanks!
Glad you like it :)
Thanks for your feedback.
