Features
  • Finds the files and folders using the most space on your hard drive
  • VERY Fast! WizTree reads the master file table (MFT) directly from NTFS formatted hard drives (similar to the way Everything Search Engine works)
  • Visual Treemap allows you to spot large files and large collections of smaller files at a glance
  • Finds the largest files on your hard drive. Every single file on your hard drive can be sorted in order of size.
  • File Name Search - quickly locate files by name or wildcard match
  • Sort the contents of your entire hard drive by folder size and optionally delete files and folders
  • Scan ALL hard drive file system types (NTFS, FAT, FAT32, network, etc) and/or individual folders

What is WizTree?
WizTree is the world's fastest disk space analyzer. It scans your hard drive and shows you which files and folders are using the most disk space. It does this in the FASTEST way possible - you simply won't find any other application of this type that's quicker! Use the information WizTree provides to quickly locate and remove "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?
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 3.00 (31 August 2017)
  • 64 bit version now available. The 64 bit version can work with extremely large MFT files.
  • "Allocated Size" now displayed for each file/directory. This is the amount of actual disk space used by the file including any additional named data streams attached to the file.
  • NTFS "Hard Links" now supported. A hard link is an identical copy of an existing file where the file contents use the same area on the disk for storage (to save space). If WizTree detects a hard link the allocated file size will be displayed in parentheses in gray text. Hard linked files sizes are only added once when calculating "Allocated Size" totals and sub totals. This will give a 100% accurate total of the actual disk space used by folders that contain many hard linked files (such as C:\Windows\System32 and C:\Windows\WinSxS)
    (Note that hard links can only be detected on NTFS drives when WizTree is running with admin rights)
  • A selected file count and total size appears in the status bar
  • Hover over any file to have the full name displayed in the status bar
  • MFT dump now appends volume information (bytes per cluster, sector, MFT record etc) to the end of the MFT file data. WizTree now reads this information from the MFT file if it's available instead of making any assumptions which if wrong would lead to incorrect MFT parsing.
  • Background file monitoring for deleted files now uses a different more robust method. If WizTree detects that a file or directory has been deleted it will put a red line through it and remove it from the totals.
  • File view filtering is now even faster than before
  • Fixed some UI glitches when selecting files via keyboard on the File view
  • WizTree can now handle drives containing highly fragmented MFT files
  • MFT processing has been optimised so WizTree is even faster than it was before!
  • Full translation support added. Click here to find out how to add a translation.
