Neodisk vs TreeSize

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.

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.
