Or the short form, WinDirStat is a disk usage statistics and cleanup tool for various Windows versions. And it is a free tool.
My take: Most of our files are scattered around the whole computer, some buried within C: drive, some in other drives. Then one day you wake up to a shock that one of the drives is full. Well, I’m just being dramatic here.
Point being, the tool helps you find those files deep within folders and folders where you forgot to visit in a long time. But, it is taking space. You may also have duplicate files. This tool will drill down to folders, extensions, treemaps which represents each file as a colored rectangle, the area of which is proportional to the file’s size. And rectangles are arranged in such a way that directories again make up rectangles, which contain all their files and sub directories.
To begin, you need to head to the website (link below) and download the file, click on the WinDirStat from your start menu.
The tool will ask to Select Drives (shown above). You can select all or Individually. In my example, I have selected C: drive.
Once selected, WinDirStat will start scanning your C: drive and depending on your disk size, it will take couple of minutes. With my 1TB hard disk, it took nearly 5 minutes.
After scanning, the directory list which resembles the tree view (top left) of Windows Explorer but is sorted by file/subtree size. I like the treemap view (bottom, various colors), which shows the whole contents of the directory tree right away. What you also get is an Extension list (top right) which serves as a legend and shows statistics about the file types.
You can go into folders by looking at file sizes, like example above, I have selected a Video file. If selected, the treemap also highlights (bottom left, white square). So what it means, most aqua green boxes seen in the treemap represents video file types. The dark blues are Local disk. All the greys represent .JPG files, you get the point.
You can right click on a folder, file and perform various tasks. Like you can copy the path, open in Explorer, Delete to recycle bin or delete permanently.
WinDirStat can be downloaded from here.
