A modern disk space analyzer for Windows that visually maps your storage and uses AI to help you quickly find and clean up unnecessary files.

StorageRadar maps your disk, shows blocked paths instead of hiding them, lets you dry-run cleanup, and compares what changed over time. Scan data stays local, while analytics and diagnostics remain separately controllable in settings.




Help you to view at a glance all the folders, files inside them and the space occupied by them on your system

FreeUpDisk is a free disk space analyzer and cleanup tool for Windows and Mac. Its core feature is a treemap visualization: a visual map where every file and folder on your drive is represented as a colored rectangle, with size proportional to how much space it occupies.
