What is WizTree?
WizTree is a disk space analyzer utility for Windows and macOS made by Antibody Software Limited. It scans a hard drive and displays which files and folders consume the most space, using a visual treemap and a sortable file list, so users can locate and delete large files to free up storage.
WizTree scans NTFS drives by reading the Master File Table directly, bypassing the operating system to return results in seconds instead of minutes. It shows a visual treemap of disk usage, a sortable file-size list, and a duplicate-file finder. WizTree is free for personal use; commercial use requires a paid supporter code license.
Standout feature: Reads the NTFS Master File Table directly instead of walking the file system through the OS, which the vendor claims makes scans up to 46x faster than WinDirStat.
Biggest weakness: Its speed advantage from direct MFT reading only applies to NTFS drives on Windows; the macOS version and non-NTFS scans (FAT, network drives, USB) don't get the same shortcut, and commercial use of any size requires a one-time supporter code purchase rather than a subscription with ongoing feature updates.
