WizTree is a very high speed disk space analyser utility for Windows. It scans your hard drive and shows you which files and folders are using the most disk space. Your entire hard drive"s file system is displayed visually, making it very easy to locate large files and folders. Use the information WizTree provides to quickly locate and remove "space hogs" from your hard drive.
WizTree can scan all hard drive types supported by Windows (NTFS, FAT, FAT32, network, etc).
WizTree key features:
- Lightning-Fast Analysis - Scans NTFS drives by reading the Master File Table (MFT) directly—bypassing Windows—for speeds far beyond traditional scanners.
- Works with NTFS, FAT/FAT32, USB drives, network shares, and even MTP/PTP devices like cameras or smartphones.
- Shows your files and folders in an intuitive treemap layout, making it easy to spot large or space-consuming items at a glance.
- Easily locate the biggest items and detect duplicates based on name, size, and optionally date.
- Quick File Search & Filtering - Supports name/type searches (including wildcards), and lets you include or exclude specific files or folders for refined results.
- Export file or MFT data to CSV for analysis or sharing, and re-import data back into WizTree for comparisons or tracking.
- Command-Line Support - Enables automated exporting of CSV or MFT data—ideal for scripting, auditing, or integration with other workflows.
