About WinDirStat
WinDirStat scans drives and visualizes every file as colored blocks in a treemap — spot the 40 GB forgotten folder instantly. Still the classic answer to full disks.
WinDirStat is completely free and open source (GPL) — no trials, no subscriptions, no locked features. Always download from the official website to avoid bundled malware.
Free alternative to: TreeSize Pro (paid)
