WinDirStat

WinDirStat transforms complex disk usage data into an easy-to-understand visual format. Its signature treemap chart represents files and folders as colored rectangles, with sizes proportional to their disk space consumption. This graphical approach allows you to immediately identify the largest files and most space-intensive directories. By providing a clear, at-a-glance overview of your storage, WinDirStat simplifies the process of cleaning up your drive, helping you delete clutter and organize your files for better computer performance.
