Alternatives to QDirStat

A Qt-based graphical disk usage analyser with a directory tree and treemap view. The listings below can replace it for an important use case. Each note says what changes if you switch.

Replacements

Listings that take over the same core job as QDirStat.

  • 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

    Shows disk usage as concentric rings you can click into.

    FreeOpen sourceWindowsLinux

    Filelight shows usage as clickable concentric rings rather than a treemap, runs on Linux and Windows, and pulls in KDE libraries.

  • GrandPerspective

    Treemap view of disk usage on macOS.

    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

    WinDirStat offers a similar treemap with duplicate finding and saved scans, but runs only on Windows.

  • 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.

  • DaisyDisk

    Interactive sunburst map of disk usage for macOS.

    PaidProprietarymacOS

    DaisyDisk uses an interactive sunburst map on macOS and is paid, closed-source software instead of open source.

  • gdu

    Find large directories with a terminal disk-usage analyzer.

    FreeOpen sourceWindowsmacOSLinux

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

Also worth comparing

These listings name QDirStat as their own alternative, so the relationship runs both ways.

    A Windows disk space analyzer that classifies files on local disks, network shares and NAS devices.

    FreemiumProprietaryWindowsCommand line

    QDirStat is GPL-2.0 open source for Linux and macOS with a treemap and tree view, but there is no Windows version.

  • Duc

    A set of tools that index disk usage into a database and show it in several interfaces.

    FreeOpen sourceLinuxCommand line

    QDirStat gives a graphical treemap and tree view on Linux and macOS under GPL-2.0, scanning directly instead of browsing a database index.

  • FolderSizes

    A Windows disk space analyzer that reports folder sizes and finds large, old and duplicate files.

    FreemiumProprietaryWindows

    QDirStat is GPL-2.0 open source with a treemap and tree view on Linux and macOS, and it has no Windows version.

  • OmniDiskSweeper

    A free macOS utility that lists the files on a drive from largest to smallest.

    FreeProprietarymacOS

    QDirStat is open source and combines a tree view with a treemap on macOS and Linux, though its interface is dense for casual users.

  • WizTree

    Finds what is eating a Windows disk in seconds by reading the NTFS master file table directly.

    FreemiumProprietaryWindows

    QDirStat is an open-source tree and treemap analyser for Linux and macOS, with no Windows version and a dense interface.
