eDirStat vs TreeSize

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.

TreeSize analyzes files and folders to show how storage is used on Windows desktop systems. Scans can cover local drives, network shares, cloud storage, USB drives, SD cards, and external hard drives; treemap views and file-type breakdowns help present the results. Depending on edition, results can be exported to PDF, Excel, CSV, HTML, or SQLite. Professional adds server scanning, command-line parameters, scheduled scans, and automated reporting. Other listed tools include deleting, moving, bulk renaming, archiving, duplicate finding, and deduplication. TreeSize Free is for private, non-commercial use on Windows desktop and cannot be used on Windows Servers. The editions run on Windows Desktop and operate on-premise; the maker says data does not leave the computer or site and is not shared with third parties. Personal and Professional have 14-day free trials, while SpaceObServer Enterprise has a 45-day trial. Annual prices listed include 20.40 € per user for Personal and from 40.80 € per user for Professional. The Free plan is listed at free.
