Our verdict on WizTree
WizTree is a Windows disk-space analyzer for people who need to understand how files and folders consume storage. It scans hard drives, network drives, USB drives, MTP/PTP devices, and individual directories, then presents the results in visual treemap and tree views. File-name and file-type searches with wildcards, duplicate-file detection, clipboard copying, and CSV import and export make it suitable for personal storage cleanup as well as commercial disk analysis.
The pricing structure keeps personal use accessible through the Free Version, which costs US$0 one time and includes the visual treemap, file view and search, CSV export/import, and duplicate-file detection. Commercial use requires a paid option. The Individual Supporter plan costs US$25 one time and adds commercial use, standard support, a perpetual supporter code, and free upgrades for one year. The Enterprise License costs US$750 one time and provides unlimited single-site use, commercial use, and priority support. Commercial pricing varies by organization size and site count, so the right license depends on how the software will be deployed.
WizTree’s strength is focused storage analysis rather than broader system management. Command-line CSV and MFT export functions support more structured workflows, while network, USB, and MTP/PTP scanning extends its reach beyond a single internal drive. It is a strong choice for Windows users who want quick visual insight into files and folders, especially when duplicate detection or external-device scanning matters. Organizations needing commercial use should account for licensing, and users on platforms other than Windows should choose a different tool.
