WizTree

WizTree is a file and folder storage analyzer for Windows and macOS, best suited to people who want to locate large space users across different kinds of drives. Its treemap, file-type breakdowns, and CSV export make the results useful in several ways, though it does not report application sizes.

Overview

WizTree scans files and folders, then shows their sizes in a visual treemap and by file type. It can scan external drives, non-NTFS drives, and network drives. On NTFS volumes, it reads the Master File Table directly; the publisher claims this is 46 times faster than WinDirStat. That is a stated comparison, not a guarantee for every drive or setup.

Hard-linked files are counted once, which avoids inflating storage totals. File details can also be exported to CSV for review outside the app. The missing application-size reporting matters if you want to identify storage use by installed program rather than by files and folders.

Key features

• Treemap: Displays file and folder sizes visually, helping pinpoint large storage users in a scan.
• File-type breakdown: Adds a way to examine storage by file type alongside the file-and-folder view.
• Broad drive scanning: Supports external drives, non-NTFS drives, and network drives, in addition to direct NTFS scanning.
• CSV export: Lets users take file details into a spreadsheet or another tool for further review.
• Hard-link handling: Avoids counting hard-linked files more than once.

Pricing

Personal use is free. Paid licenses are based on the organization’s total staff, regardless of how many people use WizTree, and each physical business location requires its own license. The supporter-code licenses are perpetual, with upgrades to versions released within one year of purchase covered. The listed once-off business licenses are the clearest fit for organizations that want a perpetual code without ongoing billing.

• Individual Supporter Code — $25 a month: A perpetual license for one individual; the purchase supports development. Supporter codes do not expire, and upgrades are covered for one year after purchase.
• Micro Business Supporter Code — $100 a month: For organizations with up to 5 staff; a separate license is required for each site.
• Small Business Supporter Code — $200 a month: Covers organizations with up to 20 staff, with a license required per site.
• Medium Business Supporter Code — $350 a month: Covers up to 50 staff, with a license required per site.
• Large Business Supporter Code — $500 a month: Covers up to 100 staff, with a license required per site.
• Enterprise Supporter Code (single site) — $750 a month: Unlimited use at one site, with priority support for enterprise license users.
• Enterprise Supporter Code (multi site) — $1,800 a month: Unlimited use across multiple sites, with priority support for enterprise license users.
• Individual — $25, paid once: A supporter-code license for one individual.
• Micro Business — $100, paid once: For organizations with up to 5 staff.
• Small Business — $200, paid once: For organizations with up to 20 staff.
• Medium Business — $350, paid once: For organizations with up to 50 staff.
• Large Business — $500, paid once: For organizations with up to 100 staff.

The organization plans are constrained by staff count and site licensing, so a company with multiple locations must account for a separate license at each physical site. Payments are processed by PayPal or Stripe, with AliPay also offered during purchase.

Platforms

WizTree is available for Windows and macOS. Its drive support spans NTFS, non-NTFS, external, and network drives, making it relevant for people whose storage is not limited to a single local NTFS volume.

Who it's for

WizTree suits home users who want personal storage analysis at no cost, and organizations that need file-and-folder scans with visual and exportable results. Its per-staff and per-site licensing gives businesses defined license tiers, while the enterprise options cover unlimited use at one or multiple sites. It is a weaker fit for anyone who needs to see disk usage grouped by installed application.

Pros and cons

• Pros: Scans more than local NTFS volumes. Support for external, non-NTFS, and network drives broadens its usefulness for mixed storage setups.
• Pros: Multiple ways to inspect results. Treemap viewing, file-type breakdowns, and CSV export serve visual review, categorization, and follow-up analysis.
• Pros: Personal use is free. Individual users can scan without buying a license.
• Cons: No application-size reporting. Users looking for storage totals by installed program will need another tool.
• Cons: Business licensing can multiply by location. Each physical site needs its own license, and the staff count basis includes the whole organization whether or not every employee uses WizTree.

Verdict

Choose WizTree if you want free personal file-and-folder storage analysis on Windows or macOS, especially with treemap viewing, file-type breakdowns, and scans across external, non-NTFS, or network drives. Its main limitation is the absence of application-size reporting, which makes it the wrong pick when installed-program totals are central to the decision.
