eDirStat review
A broad, open-source storage analyzer for users who want visual scans and cleanup tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
eDirStat is a Rust-based disk usage analyzer for Windows, macOS, Linux, and the web. It is aimed at users who want to understand storage through interactive treemaps, charts, file-extension statistics, and file-level analysis. The project is open source under the MIT license, with local filesystem scanning, duplicate detection, snapshots, external-drive support, and file-management operations included in its feature set. A browser-based snapshot viewer also extends access beyond the desktop application.
Pricing depends on how the software is obtained. The source code is free under the MIT license, while official precompiled binaries are distributed as paid downloads. The listed Mac App Store plan is priced at 9.99 and includes disk usage analysis, interactive treemap visualization, and duplicate-file detection. This makes the project suitable for users comfortable with open-source distribution, while the Mac App Store edition provides a paid route for the macOS version. The published category specifications also include a free plan, treemap viewing, file-type breakdowns, external-drive scanning, report export, and scans covering files and folders.
Its standout strength is the combination of visual analysis and storage-management depth. Seven-stage duplicate-file detection, compressed filesystem snapshots, NTFS Master File Table scanning, and scanning for external drives and mounted shares give it a wider scope than a simple folder-size viewer. Bulk deletion, trashing, and linking operations add practical follow-through after analysis. Users who want an open-source tool spanning Windows, macOS, Linux, and web access should find the feature coverage compelling. Those seeking only a minimal, single-platform disk summary or a uniformly packaged paid application may prefer a narrower alternative.
