WizTree: Fast Disk Analysis with Visual TreeMap

WizTree is a Windows disk space analyzer that prioritizes speed and accuracy to help locate the largest files and folders on a drive. It combines direct file-system access on NTFS volumes with an interactive TreeMap visualization to make space reclamation and storage auditing straightforward.

Core features

• Direct MFT access for speed: On NTFS drives WizTree reads the Master File Table (MFT) directly from disk, producing results in seconds rather than minutes.
• Visual TreeMap: A clickable TreeMap shows file- and folder-size distribution graphically, enabling rapid identification of space-intensive items and immediate drill-down to individual files.
• Accurate accounting: Hard links are handled correctly so sizes are not double-counted and reported totals align with Windows disk usage figures.
• Support for non-NTFS and network drives: Optimized scanning routines allow analysis of non-NTFS volumes and mapped/network drives, although NTFS remains the fastest option.
• Search and filters: Built-in search and filter tools make it possible to target specific file types, recent files, or name patterns for quicker cleanup.
• Export and cleanup actions: Files can be deleted or moved from within the interface and reports can be exported to support planning larger maintenance tasks.

Typical workflow

1. Scan a drive or folder to generate a TreeMap and sortable file/folder list.
2. Click a block in the TreeMap to expand folders and inspect file properties such as size and date.
3. Apply searches or filters to narrow results to large media files, installers, or stale data.
4. Delete, move, or export findings to reclaim space or document storage usage.

Use cases and audience

• Home users seeking a fast, low-friction tool for freeing disk space on personal PCs.
• IT staff and technicians performing quick disk audits across multiple workstations.
• Organizations that require reliable disk-usage reports; WizTree is used by a range of large companies, including Meta, Valve, CD Projekt Red, Activision, Panasonic, and others.

Limitations and distribution

• Optimal performance depends on NTFS; scans of non-NTFS or network locations are supported but generally slower than NTFS MFT reads.
• The application is free for personal use. Commercial use is supported via purchase of a Supporter Code, and larger organizations are expected to acquire an Enterprise license for unlimited deployment.
