Finding large files with WinDirStat

Today I realised I was running short of space on one of my drives. With larger disks and online backup services it is not such a common problem as it use to be, but when it happens Windows still doesn’t offer a simple and intuitive way to find the largest files that are causing the problem.  Step in, WinDirStat!

WinDirStat (Windows Directory Statistics)  is a free program that makes finding and removing large files an easy, almost pleasing experience. It displays the contents of your disk as a colourful chart of grouped rectangles that helps you to easily spot where all your space has gone.

WinDirStat in action

WinDirStat (Windows Directory Statistics) cam be downloaded from here.

WinDirStat is, as the name implies, for Windows only, all versions,  it is quite old now so I don’t know if it works on Windows7 (thank you Brian Jacob). WinDirStat is based upon KDirStat which is still available for Linux systems. There is also something similar called GrandPerspective for the Mac.

I have used this software several times in the past and knew I needed it again today, in looking for it I realised it is not referred to in many places so, as much for my own benefit as for yours, I thought I would make it that little bit easier to find by blogging about it here.

Once downloaded, before it can display your disk in its useful coloured box format, WinDirStat  needs to look at your disk to see how much space all the files  are taking up. When you first run the program you are offered the choice between scanning all drives or selecting an individual drive (or even just a folder), if you are only concerned with one drive it will obviously be a lot faster to view only that one.

The next screen you see is  really just telling you that the software is getting the information it requires, the display shows pacman chomping through your folders, but rest assured he is not eating any files.

Once WinDirStat has finished analyzing your hard drive you get to see what I find to be the most useful representation of your hard drive for determining which files and folders are taking up the most space on your system. As shown above, the main window is full of coloured boxes and rectangles, each one representing an individual file on your system, grouped into larger rectangles representing the folders that they are within. As you move your mouse over the colourful graph you see the file names appearing in the status bar at the bottom of the screen. Click on any box and the traditional file manager view at the top of the screen will jump to that file. If you want to see how much space the entire folder that that file sits in is taking up simply click on the folder in the top left file manager and you will see the box representing its disk usage highlighted on the main chart.

Right click on any box or rectangle representing a file in the main window and you get the option to zoom in or out of the picture, giving you more detail on those numerous smaller files on your system.

Right clicking on any file or folder in the top-left file manager view gives you the option to delete it or open an explorer window onto it. When a file is deleted using this menu the image below is automatically updated to accommodate the change.

I hope you find this program as useful as I do!

One thought on “Finding large files with WinDirStat”

  1. WinDirStat can be used on Windows 7 systems. I used it to delete a lot of the “bloatware” that came on my new computer to maximize the space on my hard disk. This program is great!
