What makes WizTree so fast?

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.

FEATURES

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.

  For 32 and 64 bit versions of Windows 11, 10, 8, 7, Vista, XP, Server (2003 and later)
