Just found an open-source utility that maps out disk usage: WinDirStat <http://windirstat.info>

You let it run and it shows an overview of all of your disk usage. It also lets you delete selected files — nice!

The largest rectangles in the drive map are the largest files, click on one and it shows you its info and lets you manipulate it.

I have been working with laser scan point clouds recently. We fill up disk space very quickly; I think this will come in handy.

  1. The problem with treemaps is that you have no idea what it represents. You have to click on it to find out

    Thats why I use Directory Report instead
    It looks just like the MS-Explorer but always shows the folder's size

    No extra clicking and no geussing
