Disk Usage Analyzer vs WinDirStat

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.

WinDirStat is a free, open-source disk usage analyzer and cleanup assistant for Microsoft Windows. It scans drives, folders, network shares, and MTP devices, then shows results in a file tree, extension list, treemap, flame graph, or sunburst. Users can compare logical and physical sizes, search by name, size, type, or owner, and compare file content hashes to locate duplicates. Scan snapshots can be saved and reopened; reports can be exported as CSV or JSON, and scans can be automated. The software includes cleanup tools and attempts to recover deleted files from local NTFS, exFAT, and FAT drives. Storage Analytics estimates monthly savings for configurable storage tiers from file sizes and modification ages, but does not move files or configure a storage service. Permission entries can be scanned and exported, though reports do not determine an individual user’s effective access through all group memberships. Downloads include Windows x64, x86, and ARM64 installers, portable archives, and a Microsoft Store package. The project lists support for Windows 7 through 11 and Windows Server 2008 R2 through 2025; other versions are unsupported.
