    It's way more faster than WinDirStat

    All the comments about WizTree being faster are outdated, since the 2.0.1 in october 2024 WinDirStat is as fast if not faster than Wiztree. Reasons that make WindirStat a better option include:

    • No annoying vibrating animated donation button every time you use it.
    • It's open source.

    only real downside is the lack of a dark theme.

    The color scheme is sober and does not hit the eye - better UI

    Windirstat is great but this is a bit simpler to understand visuals with the labeled squares etc. It's portable by design and there's no nagware animated donation buttons just like WinDirStat.

    It hasn't been updated in a while and might give you an error message sometimes but other than that it's an excellent alternative. You should have both this and WinDirStat installed.

    The program seems to be no longer updated. Last version, 2.13, released in July 2012, is fully working and can be still downloaded from the official website.
