Spec score 8.5 #13 of 105 in Disk Space Analyzers

What it is

eDirStat is a cross-platform disk usage analyzer that scans files and folders and visualizes storage use. Its interactive treemap supports breadcrumb navigation and subfolder zooming, while charts group results by file type and duplicates. The directory walker distributes directory branches across CPU cores. Duplicate identification uses a seven-stage process that includes file size, partial hashes, multi-range sampling, full BLAKE3 hashing, and timestamp checks. After reviewing results, users can batch trash or permanently delete files, or replace duplicates with hardlinks. Scans can include external drives and mounted SMB/NFS shares, and directory states can be saved as compressed .edst snapshots for inspection in a browser-based WebAssembly viewer. The maker says the app runs offline without telemetry, analytics, network beacons, or crash-reporting SDKs, and that file changes require manual review and confirmation. It is open source under the MIT license. Windows, macOS, and Linux downloads are listed; the itch.io download costs 4.99 USD once and includes lifetime updates and unlimited personal and corporate devices. The Mac App Store edition requires macOS 12.0 or later and Apple M1 or later.
