Mac memory allocation visualization tool?

[asterroc]

Somebody on my flist posted a program that would let me see where all my memory is being allocated on my Mac. The problem is that I've got only a couple Gigs of HD space left (used 89 Gigs of 93), and I just moved all my document files off onto an external HD, and that was only 2-4 Gigs. So I want to know if the rest are images, audio, programs I don't use, or what. Help!

There's a trial version that lets you see stuff; the pay version gives you a delete button. (No kidding.)

I've generally been quite pleased with their software, although I hardly ever use this particular application. (OmniGraffle is the bomb, and the outliner isn't bad either.)

Hm, I know I've seen a graphical program, that colors each type of file a different color.

Huh, I've got Omni Outliner installed apparently, and I've no clue what it is. I should delete that

FYI, it's likely that data (e.g. video and audio), rather than applications, are taking up the bulk of your space.

There was a huge chunk taken up by podcasts that I don't listen to. My photos are huger, so I may delete a bunch of those, since I upload them all to Flickr anyway.
