WinDirStat is probably the best free disk space analyzer tool you can find. It displays all the information you need to understand what's taking up valuable disk space on your internal hard drives, flash drives, and external hard drives.

WinDirStat doesn't just show you what's occupying all the space - it also lets you setup cleanup commands and manually delete data, all from within the program.

My Thoughts on WinDirStat

It can be frustrating to have a hard drive with little remaining disk space, but WinDirStat truly makes it a breeze to understand which folders and files are taking up all that storage. And not only does it show you this information, but it lets you act on it by removing the large (or small) files and folders to clear up space.

Since custom cleanup commands are supported, you can add up to ten different commands that you can run on folders or files. The idea is to add functions to the program that aren't natively supported, which is a great idea. For example, instead of moving numerous large files from one small hard drive to a different bigger drive, you could just build a simple command that automates it for you in one click.

I know there are other free disk analyzer tools out there but you should definitely try WinDirStat first so that you can get a feel for how useful it is for figuring out what's taking up so much disk space.

    More About WinDirStat

    After using WinDirStat for a while, these were some of my major takeaways:

    • WinDirStat works on Windows 10 down through Windows 95
    • You can scan one, multiple, or all internal hard drives, flash drives, and external hard drives at once, or just one single folder
    • One available view is given so that you can browse through folders and files like you would in Windows Explorer, except that WinDirStat sorts the folders not by name or date but total size
    • There's also a sortable extension list that shows which file formats (like MP4, EXE, RAR, etc.) are taking up the most space. It includes a description of the file type, what percentage of the total available space that the format is using, and how many files of that type are on the drive/folder
    • The extension list all serves as a key to understand the treemap, which is a visual representation of all the files on the drive and their respective proportional size to every other file (the files represented as larger blocks take up more disk space than the files shown as smaller blocks)
    • You can quickly copy the path to any file or folder
    • The Cleanup menu provides a way to open files and folders from within WinDirStat, as well as open the folder that a file is stored in, launch Command Prompt at a certain location, delete files/folders, and view the properties of an item
    • You can change the colors for the directory listing from within WinDirStat's settings, as well as display the total time it took for a scan to finish
    • The brightness, height, style, and other options for the colored, boxed treemap can be customized
    • Custom command-line commands can be setup to do anything supported by the Windows command-line, like delete all the TMP files in a folder you've selected, send all of a folder's file names to a text file, etc.
    • WinDirStat will display only the first 2 million subitems in a directory (which shouldn't be a problem for most people), as well as files and directory trees that aren't any larger than 8.3 TB
