I installed CCleaner about a week ago and I vaguely remember seeing a option that was sort of like windows explorer but integrated into CCleaner. The part about it that I was most interested in was the fact that it showed the size of each folder. For the life of me though, I cannot find this option in CCleaner and I am beginning to think it was never there in the first place!
That just lists the file size of each file analyzed. What I remember seeing was a Windows Explorer type view of all the folders (with the + and - signs) and the size of each folder as I branched up and down.
