WinDirStat – Find Out where all your disk space has gone

WinDirStat 2007-08-22_115113 Version Tested :
Compatibility : Win 2000, XP, WS 2003, Mac OS X 10.3 and later, Linux all

Description : Scans selected drives and creates a graphical representation of all the files, with colour coded file types and the ability to zoom in and out between folders. Gives an over view of files, their type, size and location on your computer.

I found this amazing app quite a while ago, and I simply can’t believe I haven’t already shared it with you. For that I am sorry. This is one of the most beautiful and easy to use apps I have ever used. It also does exactly what you want it to.

If you like to understand where all that space on your new 500GB hard disk went so fast, then this WILL explain it to you. Not just explain, more like shout very loudly at you, and put on a firework show with style that you can’t really ignore. It makes sure you understand exactly where that precious space has gone, and what file type is taking up the most space. It only took 13mins to scan my whole computer, and that’s well over 300GB.

As you can see from the screen shoot (even without enlarging it), that the GUI (Graphical User Interface) is very clear and nicely laid out. At the top left, we have the file system, like your already used to in windows, and to the left of that, the file type colour code system (auto generated based on type that takes up the most space). Then, below those, we have the TREE MAP, simply amazing, and completely sells this app to me as a keeper.

If you load up the screen shoot in a new tab, you can see, I like my music (and yes, I have bought a lot of music). MP3 format has been colour coded as blue. If you look on the tree map, you can see the masses of blue files, all rather small. You can also see that I have a large 7z Archive, which happens to be my music back up. By now you get the idea, files are colour coded, and grouped in folders in the display. There’s just a few more functions though.

In the Tree Map, you can click on any of the little coloured box’s, and it will take you to that file in the file system at the top and show you what file type it is. Not only that, but when you hover over any of them, it displays the file path in the bar at the bottom of the app. The reverse also works, you can select files or folders in the system file view, and they will be highlighted in the Tree Map.

Yes, there is even more! In the file type panel, you see the scroll bar? Well if you scroll across, you also get the number of bites (in GB/MB all the way to bites) each file type takes up on your selected drive that was scanned. The percent it takes up, and also how many files. This information can be extremely useful. I can tell I have 20GB’s of zip files, but only 9 files in total.

But wait I hear you say, there is also a scroll bar on the left panel, what secrets does that hide? Well my friends, yet again, some useful info for you on your folders. The sub tree percentage can come in handy, as it shows you with a graphical and numerical representation of the percentage each folder takes up of its parent folder. So for example, My Computer is 100%, but the F Drive accounts for 74.8% of my total storage. Also it shows the size of each folder and file, how many items are in each folder, number of files, number of sub folders, date and time last changed, and finally, any attributes, like read only, or encrypted.

You can select to view free space or not, your preference, but default is set to not show free space. The views are rather flexible, you can turn on and off each panel. It tops off with an “email to owner” function, which I could not get to work, but I cant see any use for it either.

Finally, it believes it has the ability to “clean up”, however I see this as a bit of false advertising, as you have to configure this manually with a command line. Fine if your that way inclined.

Conclusion : Baring in mind this app is somewhat a copy from a Linux app that does the same, its rather good. If you want to really SEE where your space has gone, this app SHOWS you. One to keep. The Linux and Mac versions are made by different people and have different sites, given below.

  1. I prefer the free (old) version of spacemonger to windirstat. Its main advantage is that it shows the names of the folders/files in the treeview itself.

  2. Got to be, by far, the most Trippy way to see where all the fat is on your HD’s !! LOT’s of info (I’m an info freak), and it’s Free !!
    Thanks Appaholic !!!

  3. totally dude, tripped me right out when i saw all the fat is on my HD! crazy stuff there, it dont trip me out as much as this site though, feels like im on drugs or something, hahah.

  4. I prefer Directory Report
    Looks just like the MS-Explorer but shows the size of directories.
