What eDirStat is
eDirStat is an open-source, MIT-licensed disk usage analyzer for Windows, macOS, Linux, and web viewing. It scans files and folders, then presents storage use in an interactive treemap with breadcrumb navigation and subfolder zooming. File-type and duplicate charts provide additional views, and reports can be exported. A work-stealing multithreaded walker distributes directory branches across CPU cores. Duplicate detection uses seven stages, including size checks, partial hashes, multi-range sampling, full BLAKE3 hashing, and timestamp verification. After review, users can batch trash or permanently delete files, or replace duplicates with hardlinks. Scans can include external drives and mounted SMB/NFS shares. Compressed .edst snapshots can be inspected in a browser-based WebAssembly viewer. The maker says eDirStat runs offline without telemetry, analytics, network beacons, or crash-reporting SDKs. File changes require manual review and confirmation. The itch.io download costs 4.99 USD once and includes lifetime updates for unlimited personal and corporate devices.
