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!

Please help

Hi hhara, and welcome to the forum.
In the Cleaner section you can do the following.
Right click on a blank space of results and view detailed results for all files.
Alternately, you can double click or right click a single line to view that lines detailed results only.

In Tools -> Uninstall the publisher, install date and file size are shown in Vista and Windows 7.

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.

The only time I've seen a Windows explorer view is when I'm including or excluding files and folders.

Maybe something happened that only happens the first time you run it? I am probably imaging this but I could have sworn it was CCleaner!
