How to find and delete large files quickly with WizTree

WizTree is a lightning-fast disk space analyzer that scans your entire hard drive to show you exactly which files and folders are eating up your storage space. Follow these steps to clean up your drive:

  1. Launch as Administrator
    Download and install WizTree. For the fastest possible scan speeds, always right-click the shortcut and select Run as administrator.
  2. Select Your Drive and Scan
    Use the drop-down menu at the top left to select the drive you want to analyze (e.g., C: Drive). Click the Scan button. The scan will typically finish in just a few seconds.
  3. Analyze the Visual Treemap
    Look at the colorful block chart at the bottom of the screen. Each block represents a file, and the larger the block, the more space that file is taking up. You can easily spot massive files at a glance.
  4. Review and Safely Delete
    Expand the folders in the top "Tree View" to see exact sizes. Once you find a file you no longer need, simply Right-Click it directly in WizTree and select Delete to send it to the Recycle Bin.

Frequently Asked Questions

WizTree bypasses standard, slow Windows API file scanning. Instead, when scanning NTFS-formatted drives, it reads the Master File Table (MFT) directly from the disk. This allows it to scan millions of files in mere seconds.

Highly recommended, but not strictly required. To access the hidden MFT and get those lightning-fast scan speeds, WizTree requires Admin rights. If you run it as a standard user, it will fall back to the traditional, slower Windows scanning method.

Yes, but proceed with caution. WizTree integrates directly with the Windows context menu, so deleting a file here is the same as deleting it in File Explorer. However, be careful not to delete critical system files located in your Windows or Program Files folders unless you know exactly what they are.

WizTree is completely free for personal use on your home computer. However, if you are using it in a commercial, enterprise, or business environment, you are required to purchase a "Supporter" license to comply with their terms of service.
