WizTree

WizTree is a very high speed disk space analyzer 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.

When scanning NTFS formatted hard drives (most modern hard drives use this format), WizTree reads the hard drive's Master File Table (MFT) directly from the disk. The MFT is a special hidden file used by the NTFS file system to keep track of all files and folders on a hard drive. Scanning for files this way completely bypasses the operating system (Windows) and provides a huge performance boost.

WizTree can also scan non NTFS hard drives, network drives, USB drives and individual directories.

Disk Space Analysis

Quickly identify what's using up the space on your hard drive and optionally delete files and folders to free up space.

Extremely Fast!

WizTree reads the Master File Table (MFT) directly from NTFS formatted drives (similar to the way Everything Search Engine works)

Multiple File Systems

WizTree can scan all hard drive types supported by Windows (NTFS, FAT, FAT32, network, etc). MTP/PTP devices like smartphones and cameras can also be scanned when connected via USB.

Visual Treemap

The visual treemap displays all files and folders visually based on their size. This allows you to spot large files and large collections of smaller files at a glance.

Find Largest Files

The "File View" lists every individual file and folder on your hard drive in order of size.

File Name Search

Quickly locate files by name or type using the file view search filter. Wildcard searches also supported (e.g. *.mp3)

Export File and MFT Data

All or selected file information can be exported to CSV (comma separated values) file or copied to the clipboard. MFT files can be extracted and dumped to a file.

Import File and MFT Data

Exported CSV and dumped MFT files can be imported back into WizTree for viewing. Great for tracking file system changes over time.

Command Line Support

Exports of CSV and MFT files can be done via command line parameters. Great for automated auditing of hard drives.
