In their own words
Neodisk
Neodisk is a free, open-source disk space analyzer for macOS and Linux. It scans files, folders and applications, then presents storage usage in treemap, sunburst and outline views. Zooming, folder navigation, fuzzy search and keyboard navigation help you move through a scan. Analysis includes largest-file discovery, file-type statistics, an age heatmap and duplicate finding verified with content hashes. Neodisk is read-only: available file actions are revealing an item in Finder or Files, opening it and copying its path. Completed scans persist as snapshots that can be reopened. On macOS, the Changes tab records additions, deletions, renames and size changes since the previous scan. Optional Google Drive access reads quota and metadata without reading, downloading or changing file contents. macOS requires version 14 or later on Apple silicon or Intel. Linux AppImages support x86_64 and ARM64, but Linux lacks duplicate and changes tabs, cloud-drive scanning and incremental rescans.
WinDirStat
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.
