Instead of WizTree
WizTree alternatives
WizTree maps files and folders in a treemap, shows file-type breakdowns, scans external, non-NTFS, network, and NTFS drives, and exports details to CSV. It reads NTFS Master File Tables directly and handles hard links without counting them twice. Windows and macOS users can scan files and folders, with free personal use and supporter codes starting at $25. Business licenses depend on total staff and physical locations, while enterprise users receive priority support.

You might switch when another platform, visual style, or usage term fits your setup better. Filelight and Disk Usage Analyzer support Linux; OmniDiskSweeper focuses on macOS. TreeSize, WinDirStat, and FolderSizes remain Windows choices. Compare whether you need file-type views, reports, external-drive scanning, folder targets, commercial permissions, or trial access. Also consider each product's free-edition limits and paid entry point, then weigh those differences against WizTree's treemap, broad drive scanning, CSV export, and organization-based licensing.
