Disk Usage Analyzer vs eDirStat

Disk Usage Analyzer is a free Linux desktop app for checking how storage is used and how much space remains. It scans selected folders, storage devices, and online accounts; external drive scans are also supported. Results present folder sizes in a tree view and a graphical representation, so users can inspect how a scan’s contents are distributed. The app page directs users to install the latest version from Flathub, which lists aarch64 and x86_64 architectures. The GNOME app page lists version 50.0, released on 2026-03-13, and names Paolo Borelli, Stefano Facchini, and Christopher Davis as maintainers. Users can report issues or suggest ideas through the app’s issue tracker. Flathub labels the app “Medium Risk.” The plan is listed at free. The app page does not identify which online account services can be scanned, and it does not state security certifications or compliance details.

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.
