Find out What is Using up Your Hard Drive Space With WinDirStat

Have you ever looked at your hard disk free space, and wondered where it all went? I mean, when I bought that 250G drive, I thought I would never need more space.

WindirStat is a easy way to graphically see where all of that free space went to. I use it all the time, even on my networks, to see what is using up all of my drive space.

Of course, it doesn’t run instantly, after all, WinDirStat has to crawl through every directory on your hard drive. While directories are being updated, you are entertained with little packmen running back and forth next to the directories it is updating.


The visual representation of the files is neat, but I really look for the top half of the screen, pictured below.


Directories are listed with the largest on top, and you can continue to drill down into the subdirectories to find out what they are made up of.

This really is a great utility, and you can’t beat the price, which is free.

You can download WinDirStat from the Downloads page, also check out the WinDirStat Web Site.

  1. I always get that memory stuff mixed up. Or — hard drive space. So when it says 1 GB 667 MHz DDR2 SDRAM…what does that actually mean? And if I have 174.11 GB available, is that a lot? I know what’s taking up all my space. The Adobe Creative Suite. And photos. And music. Still can’t figure out how to get Leopard to love my external hard drive so I can get some of it off this computer.

  2. RAM is the memory where things are held temporarily, and where programs copy themselves to in order to Run. That is usually referred to as “memory”. The 1 GB 667 MHz DDR2 SDRAM is referring to RAM or Memory.

    RAM is really fast, and that’s why it is expensive.

    Hard Drive Space is usually referred to as “Storage”. It’s much slower than RAM, and is much cheaper.

    174 GB free is referring to your hard drive space, or storage. That is a lot to have available, so you should be good to go. Unless you start doing big video capture and editing projects.

    Unfortunately, I can’t really help you with Leapord, I’m a Windows guy, and don’t have any experience with Macs. If you have 174G free on the hard drive in your computer, than you can probably just use the external drive for backups.

    Hope that helped, and thanks for the comment!

  3. Hi Mike
    This looks like a great piece of software to see where all your drive space has gone.
    I spend alot of time keeeping my pc clean of things I no longer need.This looks like it
    may be a good tool to try out.


  4. Mike – love this software. I find that the visual representation of the data makes it easy to explain to clients how much hdd space they have, what is taking up that space, and how much data they likely aren’t backing up..

    Great Post.


  5. And for Linux users with KDE as desktop manager, you can use
    KDirStat which is exactly the same progam as WinDirStat

  6. Not to put down dirstat but I personally prefer Spacemonger Spacemonger’s representation of data is so much more intuitive then that rainbow blob. Unfortunately the 2.x stream is now commercial but you can still download the 1.x stream for free and it works well.

  7. On Windows I prefer SequoiaView, which is fairly similar but with a slightly simplified UI. KDirStat is necessary on Linux, though.

  8. Wow that was strange. I just wrote an really long comment but after I clicked submit my comment didn’t show up. Grrrr… well I’m not writing all that over again. Regardless, just wanted to say great blog!
