# WizTree review

A fast disk space analyzer for Windows and macOS that finds the files and folders eating up your storage.

By Noah — last updated & pricing verified September 24, 2026.

> 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.

## Facts

- Website: https://diskanalyzer.com
- Pricing: Free tier · paid from $25 one-time (verified )
- License: Freemium
- Platforms: windows, macos
- Best for: Windows and macOS users who need to quickly find and clear large files or folders eating up local disk space, especially on NTFS drives.
- 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.
