RidNacs: a folder size visualization app that integrates into Windows Explorer


RidNacs is a free disk space analysis tool that produces charts to visually represent the size that your files and folders occupy on your hard drive.

But the reason this software caught my attention, and the reason I am posting it here, is that RidNacs offers Windows Explorer right click integration, enabling you to right click any folder on-the-fly and get a size-chart analysis of it.

Which is kind of cool and can be quite handy. Explorer integration Works on both 32bit and 64bit versions of Windows.

Some PROS and a Wish list:

  • Windows Explorer context menu integration: makes it useful for on-the-fly usage, and is the reason this software caught my eye in the first place.
  • Results exportable: in various formats (XML, HTML, CSV, and .TXT)
  • Visual styles: offers a number of visual “skins” to choose from.

Wish list:

  • The ability to select multiple folders in Windows Explorer : it would be nice to have that ability. I tried selecting a handful of folders on my desktop to compare them visually against each other (via the Windows context menu entry), and was surprised that the program produced a window for each folder rather than a single one that compared all three.

The verdict: a handy little tool that does an excellent job. I will admit that when it comes disk space analyses I tend to prefer the “treemap” visualization offered by a program such as SpaceSniffer; however, there is something really cool about having the ability to right click on a folder and have its disk size be charted/visualized on the spot.
