Scanner has been discontinued. Similar apps include WinDirStat, which is free and open source. Other options are WizTree, Baobab Disk Usage Analyzer, Filelight and SD Maid SE. There's no shortage of Disk Usage Analyzers like Scanner, with more than 50 alternatives for Windows, Mac, Linux, Android and the web.




A fast, native macOS disk space analyzer that helps you find where your storage is going. Scan any folder or volume, explore results with an interactive sunburst chart and file browser, and clean up — all without leaving the app.


TreePie : a simple way to display disk usage. It shows the distribution of size in a tree of directories by using an interactive multilevel pie (sunburst diagram). Really small and simple.







fsv (pronounced eff-ess-vee) is a file system visualizer in cyberspace. It lays out files and directories in three dimensions, geometrically representing the file system hierarchy to allow visual overview and analysis.


DissectMac is a native, privacy-first macOS utility that uses an interactive treemap to visualize storage, allowing users to reclaim gigabytes in seconds through deep app uninstallation and real-time system monitoring.




Klarity is a disk space analyzer for macOS that shows where your storage went as a treemap: every file and folder is a rectangle sized to scale, so the biggest items are visible at a glance instead of being found one folder at a time.








A native Windows application for quickly analyzing disk usage and finding the files and folders that consume the most space.
