About QDirStat

QDirStat shows how disk space is used by combining a sortable directory tree with a treemap, so large files and folders stand out visually. It is the Qt successor to KDirStat, written by the same author, and does not depend on KDE libraries.

It targets Linux, BSD and other Unix-like systems as well as macOS. It suits users who want to find what is filling a disk and clean it up from a graphical window.

Strengths

  • Treemap plus tree view of disk usage
  • No KDE dependencies
  • Maintained by the original KDirStat author

Limitations

  • No Windows version
  • Interface is dense for casual users

Software that can replace QDirStat for an important use case, and what changes if you switch.

  • K4DirStat

    A KDE utility that adds up disk usage for directory trees and shows it as a treemap.

    FreeOpen sourceLinux

    K4DirStat offers the same list plus treemap view but is built on KDE Frameworks 5, so it fits a KDE desktop best and is Linux only.

  • Disk Usage Analyzer

    A GNOME app that shows which folders are using disk space, as a tree and chart.

    FreeOpen sourceLinux

    Disk Usage Analyzer is the GNOME tool with tree and chart views that also scans online accounts, but it is Linux only.

  • Filelight

    FreeOpen sourcemacOS

    GrandPerspective gives a treemap on macOS only and can compare saved scans to see what grew, with a deliberately plain interface.

  • WinDirStat

    Draws your whole drive as a treemap, so a single 40 GB file is a huge rectangle you cannot miss.

    FreeOpen sourceWindows

  • ncdu

    A disk usage analyser with a text interface, built for finding what is filling a remote server you can only reach over SSH.

    FreeOpen sourcemacOSLinuxCommand line

    ncdu replaces the graphical treemap with a text interface that works over SSH on servers without a desktop.

    FreeOpen sourceWindowsmacOSLinux

    gdu is a terminal analyzer with parallel scans that also runs on Windows, but offers no treemap.
