Replacements

Listings that take over the same core job as DiskSavvy.

  • FolderSizes

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

    FreemiumProprietaryWindows

    FolderSizes also analyses network shares on Windows and adds scheduled email reports and trend snapshots over time, with some features in the paid Pro edition.

  • TreeSize Free

    Shows which folders are eating a Windows drive, ranked largest first, without a scan that takes all afternoon.

    FreemiumProprietaryWindows

    TreeSize Free reads the NTFS master file table for quick scans and is free for commercial use, but reports, exports and duplicate search need a paid edition.

  • WizTree

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

    FreemiumProprietaryWindows

    WizTree scans NTFS drives in seconds and shows a treemap with a sorted list and CSV export, though commercial use needs a paid licence.

  • WinDirStat

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

    FreeOpen sourceWindows

    WinDirStat is GPL-2.0 open source for Windows, draws the drive as a treemap and finds duplicates by hash, without DiskSavvy's classification reports or command-line edition.

  • SpaceSniffer

    Shows disk usage as a treemap you click into, so the biggest folders and files are immediately obvious.

    FreeProprietaryWindows

    SpaceSniffer is free, portable Windows freeware with a live-updating treemap, but it lacks DiskSavvy's file classification reports and command-line utility.

  • Filelight

    Shows disk usage as concentric rings you can click into.

    FreeOpen sourceWindowsLinux

    Filelight is GPL-2.0 open source for Windows and Linux, scans network locations too, and shows usage as clickable rings, though it pulls in KDE libraries.

  • Duc

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

    FreeOpen sourceLinuxCommand line

    Duc moves the job to Linux, indexing very large filesystems into a database and browsing them through console, graphical or web interfaces under the LGPL-3.0 license.

  • QDirStat

    A Qt-based graphical disk usage analyser with a directory tree and treemap view.

    FreeOpen sourcemacOSLinux

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