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
  • Export file data to CSV (comma separated values) file or clipboard
  • Command line CSV file export
  • 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.
 
Exporting WizTree File Data to CSV File
Press Ctrl+Alt+E or right click on a file/folder and select "Export to CSV file...". The selected files and/or folders will be exported to a comma separated value file (.CSV format). The information exported will depend on which view is currently active (Tree View or File View). If no files or folders are selected then ALL files and folders will be exported.
e.g. If the main "C:\" folder is selected, then the entire contents of C:\ will be exported
If "C:\Windows" and "C:\Users" are both selected then the contents of both of these folders will be exported

Format is as follows:
File Name, Size, Allocated, Modified, Attributes, Files, Folders

For folders, the file name will always end with a "\", e.g. "C:\Windows\"
For folders, the Size and Allocated fields will be the total size of all files and folders contained within that folder.
For files, the Size and Allocated fields will be for that individual file only.
The "Allocated" value will be prefixed by a leading 0 if the file is a "hard link", indicating that it does not take up any additional space on the hard drive and should not be counted as part of the total space used.
Modified date is in format "yyyy/mm/dd HH:mm:ss"
Attributes is stored as a value and is a combination of the following values added together:
1 = Read Only (R), 2 = Hidden (H), 4 = System (S), 32 = Archive (A), 2048 = Compressed (C)
e.g. If a file is Read Only and Hidden it will have attribute value = 3 (1 + 2)
The Files and Folders values only apply to folders and show the total number of files and folders within that folder.
 
Copying file/folder data to Clipboard
Press Ctrl+Alt+C or right click on a file/folder and select "Copy file and size info to clipboard". File size and name information will be copied to the clipboard in a human friendly format, suitable for pasting into emails, support forum posts, or text documents. The files will be indented to match the current tree structure, and only currently visible files within the selection will be included.

For example, if you expand the "C:\Users" folder within the tree by clicking on the "+" next to it, and then right click on it and select "Copy file and size info to clipboard", you will get something like this copied to the clipboard:

            64.82 GB    C:\Users
            59.15 GB      C:\Users\Bob
             5.62 GB      C:\Users\Public
            19.99 MB      C:\Users\UpdatusUser
            15.75 MB      C:\Users\Mcx1
            11.07 MB      C:\Users\DefaultAppPool
             2.70 MB      C:\Users\Default
           174 Bytes      desktop.ini
                   0      C:\Users\Default.migrated
                   0      C:\Users\Default User
                   0      C:\Users\All Users

         If this function is used on the "File View" then file and size information for the currently selected files will be copied to the clipboard, in a format similar to the following:

             6.75 GB  C:\pagefile.sys
             3.81 GB  C:\System Volume Information\{579260ea-c771-11e7-9c10-b4749f719216}{3808876b-c176-4e48-b7ae-04046e6cc752}
             3.21 GB  C:\Users\Bob\VirtualBox VMs\XP\Snapshots\{086cc618-9a46-438b-acf1-d90f001990b7}.vdi
             2.93 GB  C:\hiberfil.sys
             2.23 GB  C:\$RECYCLE.BIN\S-1-5-21-4195858667-1952806270-3254110446-1001\$RYF1ZAO.vdi
 
Command Line Export
As of WizTree 3.18 it's now possible to automatically export file data to CSV file via the command line.

For 32 bit Windows:
wiztree.exe "drive/folder" /export="filename" [/filter="filespec"] [/admin=0|1] [/exportfolders=0|1] [/exportfiles=0|1] [/sortby=sortoption] [/exportmftrecno=0|1]
for 64 bit Windows:
wiztree64.exe "drive/folder" /export="filename" [/filter="filespec"] [/admin=0|1] [/exportfolders=0|1] [/exportfiles=0|1] [/sortby=sortoption] [/exportmftrecno=0|1]
(Note that 32 bit wiztree.exe will auto launch wiztree64.exe with the same parameters if it detects it's running on 64 bit Windows)

"Drive/folder" can be a drive letter like "C:" or a folder name like "C:\Windows"
Use %d and/or %t in export filename to include current date and time. %d will be replaced with date in YYYYMMDD format, %t will be replaced with time in HHMMSS format

Filter option can be used to export only files matching the file specification, e.g. "*.mp3". The entire path and file name is used when matching.
Separate multiple file extensions with | (pipe)
e.g. "*.mp3|*.wav|*.ogg"

Use the /admin flag to set desired admin mode (fast MFT file scanning is only available when running as administrator - use the /admin=1 parameter). To set WizTree up to run with Administrator rights via Windows Scheduler you will have to configure it to "run with highest privileges" and select an administrator user account to run it. Running it this way will prevent the Windows UAC popup from appearing.

By default both files and folders will be exported. Use the exportfolders / exportfiles parameters to disable file and/or folders from export.
e.g. to prevent folders from being exported: /exportfolders=0

sortoption can be
0 = sort by file name (default)
1 = sort by file size (desc), file name
2 = sort by allocated size (desc), file name

The MFT record number can be included in the export data file by using the exportmftrecno parameter. This record number can be used as a unique file ID number. Note that the MFT record number is only valid when exporting an entire NTFS formatted drive and when WizTree is launched with administrator rights.
 
Examples:

Export all files and folders in C: drive to "C:\temp\exportYYYYMMDD_HHMMSS.csv", running with admin rights (to enable MFT scan):
wiztree.exe "C:" /export="c:\temp\export%d_%t.csv" /admin=1

Export all *.mp3 and *.wav files (excluding folders) in C:\Users to "c:\temp\audiofilesYYYYMMDD_HHMMSS.csv", using non administrator mode
wiztree.exe "C:\Users" /export="c:\temp\audiofiles%d_%t.csv" /filter="*.mp3|*.wav" /admin=0 /exportfolders=0

Export all files and folders containing the word "test" on the D: drive to "f:\export\testfiles.csv":
wiztree.exe "D:" /export="f:\export\testfiles.csv" /filter="test"
 
To call wiztree.exe from a batch file script, use start /wait wiztree.exe to wait for the export to complete before moving on to the next line. If you're using 64 bit Windows then use start /wait wiztree64.exe as wiztree.exe will launch wiztree64.exe automatically and return immediately.
e.g. for Windows 32:
start /wait wiztree.exe "D:" /export="f:\export\testfiles.csv" /filter="test"
and for Windows 64:
start /wait wiztree64.exe "D:" /export="f:\export\testfiles.csv" /filter="test" 
 
Command Line MFT Dump
As of WizTree version 3.22 it's possible to dump the MFT file via command line.
 
For 32 bit Windows:
wiztree.exe "drive" /dumpmftfile="filename"
wiztree64.exe "drive" /dumpmftfile="filename"
(Note that 32 bit wiztree.exe will auto launch wiztree64.exe with the same parameters if it detects it's running on 64 bit Windows)
 
Use %d and %t in filename to have them replaced by the current system date and time (YYYYMMDD and HHMMSS format).
 
For example, to dump the MFT file for drive D:
wiztree.exe "D:" /dumpmftfile="c:\mftdumps\ddrive%d%t.MFT"

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.
