Is WinDirStat or WizTree faster?
WizTree is built around speed and its vendor claims scans up to 46x faster than WinDirStat, but WinDirStat 2.x also reads the NTFS Master File Table directly when run as administrator, so both use the same shortcut on local NTFS drives.
Neither tool gets the shortcut everywhere. WinDirStat falls back to slower folder-by-folder enumeration on network shares, phones and non-NTFS volumes, or when it runs without administrator rights. WizTree's macOS version and its scans of FAT, network and USB drives also miss the direct MFT read. The 46x figure is WizTree's own claim.
WinDirStat vs WizTree pricing: which costs less?
WinDirStat costs less for any business, because it is free for personal and commercial use under the GPL v3, while WizTree is free only for personal use and charges a one-time license from $100 for up to 5 staff.
WizTree's commercial licenses are priced by staff count at one site: $100 for up to 5, $200 for up to 20, $350 for up to 50 and $500 for up to 100, with unlimited staff at $750 for one site or $1,800 for multiple sites, both with priority support. A $25 Individual supporter code removes the donate button. Every WizTree license is perpetual but includes free upgrades only for versions released within one year. WinDirStat has no paid edition, license key or account.
Which has more features, WinDirStat or WizTree?
WinDirStat has the broader feature set, adding sunburst and flame-graph views, search by owner, saved snapshots, change monitoring, CSV and JSON export, NTFS compression, hardlink deduplication and deleted-file recovery to the treemap and duplicate finder both tools share.
WinDirStat 2.x also inspects permissions, estimates storage costs and runs command-line scans that write CSV or JSON reports, which suits scripted audits of file servers. WizTree keeps to a treemap, a sortable file-size list and a duplicate-file finder, and its listing describes the interface as utilitarian rather than aimed at less technical users. WinDirStat has no one-click junk scan, so every deletion is chosen by hand.
Does WinDirStat or WizTree work on a Mac?
WizTree works on a Mac and WinDirStat does not: WizTree runs on Windows and macOS, while WinDirStat is Windows-only and its project points Mac and Linux users to GrandPerspective and QDirStat.
WizTree's macOS version does not get the direct MFT read that makes its Windows scans fast on NTFS drives. Neither WinDirStat nor WizTree has a Linux version.
