What DiskLens is
DiskLens is a free desktop app for analyzing disk usage on macOS and Windows. It scans files, folders, and applications, then displays space usage in interactive pie, donut, radial, and sunburst charts. The app reports application sizes and file-type breakdowns and can export chart images as PNG files with watermarks and captions, along with detailed reports in various formats. DiskLens reads file names, sizes, and modification dates but not file contents. Scans run locally, and the maker says file information, personal data, and usage analytics are not sent to its servers or third parties. The app may contact its website for update checks, sending only its version. Users can reveal files in Finder or Explorer, move them to Trash or Recycle Bin, or exclude them from later scans. It supports macOS 10.15 or later on Apple Silicon or Intel and 64-bit Windows 10 or later, requiring 100 MB of free disk space on each platform.
