About & Overview: WizTree: Find What's Eating Your Disk Space in Seconds
WizTree is a blisteringly fast disk space analyzer for Windows that shows exactly what is eating your drive. Instead of crawling files one by one, it reads the NTFS Master File Table directly, mapping a full terabyte drive in seconds — then displays the biggest space hogs in a sortable tree and a visual treemap so cleanup targets are obvious at a glance.
