What DiskLens is
DiskLens is a free desktop utility for analyzing computer storage. It scans files, folders, and applications, then displays usage in interactive pie, donut, radial, and sunburst charts. The app reports application sizes and file-type breakdowns, and exports chart images as PNG files with watermarks and captions plus detailed reports in various formats. DiskLens reads names, sizes, and modification dates, 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. Users can reveal items 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 space. Linux support is planned, not available.
