There are plenty of free drive space analyzers out there – like WinDirStat, for example. If you like visuals that are a bit more subtle, give JDiskReport a try.

After the initial scan (which can take a minute or two on drives as cluttered and full as my C:), several reports are generated. You can view distribution by size, file type, and modification date, or browse a top 50 list to find your biggest space hogs quickly.

I did experience a momentary hang when switching to the ring chart in one particularly massive directory, but other than that the program worked very well. The standard pie chart, bar chart, and file views all worked without hanging.

It’s freeware for Windows (x64 as well) and Mac, and is also available as a Java Web Start app.
