At a previous incarnation of 404 we had a topic dedicated to programs users thought essential (might've been all Microsoft replacements). There was a program, I think it was a defragmenter but I can't be sure, that when it analyzed the hard drive it showed all the folders as large squares with the subfolders as smaller squares inside the larger squares. I know this is vague but does anyone have an idea of what it was?

as in where all your space has gone?

or to defragment?

Nevermind, I find stuff like it. Disk View Manager and stuff like that.
