WinDirStat analyzes Windows disk usage with interactive treemaps, large-file discovery, duplicate detection, and file-system monitoring.
About Windirstat
WinDirStat is a disk usage analyzer and cleanup assistant for Microsoft Windows. It can scan drives, folders, network shares, or connected MTP devices, and shows usage through sortable file lists, file-type statistics, and treemaps, sunbursts, or flame graphs.
It can find large or duplicate files, inspect permissions, estimate storage tier costs by file age, save scans as CSV or JSON, and run cleanup actions. Accelerated local NTFS scanning requires elevated access, duplicate hashing adds file reads, and deleted-file recovery depends on surviving metadata and file data.
