WizTree

WizTree is a disk-space analyzer for Windows and macOS, aimed at people who want to find which files and folders are consuming storage. It is most compelling when a visual breakdown and broad drive scanning matter more than application-size tracking.

Overview

A treemap makes relative file and folder sizes visible, while file-type breakdowns and CSV export offer other ways to inspect scan results. The software can scan external drives, non-NTFS drives, and network drives; on NTFS, it reads the Master File Table directly. Hard-linked files are not counted more than once, avoiding inflated totals.

WizTree’s publisher claims this NTFS approach is 46 times faster than WinDirStat. That is a publisher claim rather than a result established across every drive or system, but direct MFT reading is a clear point of distinction. One notable omission is application-size tracking, so users who want storage analysis organized around installed apps should look elsewhere.

Key features

• Treemap and file-type breakdown: See large space users visually and examine results by file type; useful for locating storage-heavy files without relying on a report alone.
• Broad drive scanning: External, non-NTFS, and network drives are supported alongside NTFS. This gives it more reach than a tool confined to local NTFS volumes.
• CSV export: File details can be exported for further review outside the application.
• Hard-link handling: Hard-linked files are counted once rather than duplicated in totals.

Pricing

WizTree is free for personal use. For organizations, license pricing is based on total staff, not just the number of people using the software, and each physical business location requires its own license. That makes the business cost depend on both headcount and site count.

The one-time Supporter Code options are $25, paid once for an individual, $100, paid once for up to 5 staff, $200, paid once for up to 20 staff, $350, paid once for up to 50 staff, and $500, paid once for up to 100 staff. These are perpetual licenses, but Supporter Codes cover upgrades only for versions released within one year of purchase. The individual option is for one person; business tiers require a separate license per site.

Monthly billed Supporter Code options are also offered: Individual Supporter Code at $25 a month, Micro Business at $100 a month, Small Business at $200 a month, Medium Business at $350 a month, Large Business at $500 a month, Enterprise single site at $750 a month, and Enterprise multi site at $1,800 a month. The business tiers cover up to 5, 20, 50, or 100 staff respectively, each with a per-site requirement; the enterprise choices provide unlimited use at one site or multiple sites. Enterprise license users receive priority support. The lower business tiers are a better fit for organizations within their headcount caps, while enterprise pricing suits organizations needing unlimited use or multi-site coverage. The free personal option remains the practical choice for individual use.

Platforms

WizTree is listed for Windows and macOS. Its ability to scan external, non-NTFS, and network drives makes it useful when storage sources extend beyond a single local NTFS volume.

Who it's for

Choose WizTree if you need visual file-and-folder storage analysis across Windows or macOS and want to export file details or inspect external and network drives. Personal users can use it free; organizations should weigh the staff-based pricing and separate physical-location licenses before adopting it. It is less suitable when application-size reporting is a requirement.

Pros and cons

• Pro: Treemap, file-type breakdown, and CSV export provide several practical ways to inspect storage use.
• Pro: Scanning covers external, non-NTFS, and network drives, and hard links are not double-counted.
• Pro: Personal use is free, with a range of business license sizes for organizations.
• Con: Application sizes are not tracked, limiting its usefulness for people who want to assess disk use by installed program.
• Con: Organizations pay according to total staff and need a license per physical location, which can complicate costs across sites.

Alternatives

TreeSize is worth considering for Windows users who want a free plan and trial. FolderSizes offers a $30, paid once personal license for home and personal network use, but that edition is unavailable to organizations. Filelight is a free option for Linux and Windows users. SizeTrend has a free Windows plan with local drive and folder scans, cleanup and storage recommendations, and file, content, and duplicate-file features. eDirStat is a free choice across Linux, macOS, and Windows. WinDirStat is another free Windows option. Disk Analyzer Pro offers a free personal edition with local-drive reports, file deletion, and duplicate-file reporting. Disk Usage Analyzer is a free alternative for Linux.

Verdict

WizTree is a strong fit for personal users and organizations that want visual, exportable disk-use analysis across a range of drive types. Its main strengths are its treemap, MFT-based NTFS scanning, and broad drive support; the main reasons to look elsewhere are the lack of application-size tracking and business licensing based on total staff and physical locations.
