Discover the Fastest Disk Space Analyzer for Windows

What is WizTree

WizTree, a rapid disk space analyzer for Windows, swiftly scans your hard drive, revealing the files and folders consuming the most disk space. Its visual display of your entire file system simplifies the identification of large items. Utilize WizTree’s insights to promptly identify and eliminate “space hogs” from your hard drive.

WARNING: Take care not to remove any files that are required for the correct operation of your PC!

What makes WizTree so fast?

WizTree achieves high performance when scanning NTFS-formatted hard drives, which are common in modern systems. It directly accesses the hard drive’s Master File Table (MFT), a hidden file crucial for NTFS file management. This method bypasses the operating system (Windows), resulting in a significant performance enhancement. Additionally, WizTree extends its scanning capabilities to include non-NTFS hard drives, network drives, USB drives, and specific directories.
