eDirStat is a free, open-source disk usage analyzer for Windows, macOS, and Linux.
What eDirStat is
eDirStat is a free, open-source disk usage analyzer for Windows, macOS, and Linux. It scans files and folders and presents storage use in an interactive treemap with breadcrumb navigation and subfolder zooming. File-type and duplicate-group charts provide additional ways to examine scan results, and reports can be exported. Its directory walker distributes branches across CPU cores. For duplicate identification, a seven-stage process uses file size, hashes, sampling, and timestamp checks. After reviewing results, users can batch trash files, permanently delete them, or replace duplicates with hardlinks. Scans can include external drives and mounted SMB/NFS shares. Directory states can be saved as compressed .edst snapshots and viewed in a browser-based WebAssembly viewer. The maker says the app operates offline without telemetry or analytics and requires manual review and confirmation before file changes. The Mac App Store edition is sandboxed and can scan only locations granted through the system file dialog. The itch.io download costs 4.99 USD once, with lifetime updates and unlimited personal and corporate devices.
