Unlike traditional disk analyzers, WizTree directly reads the Master File Table (MFT), making it one of the fastest disk analysis tools for Windows. It can scan an entire drive within seconds.

WizTree presents your storage usage visually using a color-coded treemap. Each rectangle represents a file or folder, with size indicating how much space it occupies. This makes it easy to identify what’s taking up the most room.
- File List View
You can view your files sorted by size, folder, or file type. This helps locate large, unnecessary files you may want to delete or move.
- Search and Filter Options
The built-in search bar allows you to filter files by name, type, or extension. For example, you can quickly find all .mp4 or .zip files.

WizTree lets users export data to CSV for professional reporting or long-term analysis. This is especially useful for IT admins or large organizations.

The latest versions support scanning network drives — perfect for businesses or shared environments.

Step 2: Click “Scan”
Hit the Scan button and wait a few seconds. WizTree will analyze the drive and generate a tree view and treemap visualization.
Step 3: Analyze Results

Step 4: Delete or Move Files
You can right-click any file in WizTree to open it, delete it, or view its location in File Explorer. This helps in quick and safe file management.
Step 5: Repeat for Other Drives
