WizTree is a tool which aims to help you find which files and folders are grabbing the most disk space. If that sounds a familiar idea, then it should - there are lots of programs doing the same thing - but WizTree still manages to add a new ingredient: speed.
Getting started here, for instance, works just like many similar applications, in that you'll choose the drive you'd like to check, before clicking "Scan". But rather than crawling manually through every folder, WizTree just accesses the drive's MFT (Master File Table, the NTFS index of everything the drive contains), and that means it's able to display a report in seconds (2.43 on our test PC).
The report itself opens with a tree view, which displays the folders using the most drive space. We saw that, for instance, our "Program Files (x86)" folder was using 14.3%. Why? Expanding that listed its subfolders, again in order of space consumed, and it turned out that the Steam folder was the main culprit, being responsible for 40.3% of that consumption all on its own.
And if that's not enough, clicking the "Top 1000 Largest Files" tab does precisely what its name suggests, displaying all your most space-hogging files in a single list. Basic details (size, last modified date) are visible up-front, but you can also view the file properties as usual, and there are various right-click options to open the file's folder in Explorer, open a command prompt there, or just delete it immediately.
WizTree's hard drive reporting and management features are nothing too special, then. But they're good enough to get the job done, and the program's extra turn of speed means you're more likely to use it (especially as the program is portable, so you can run it from just about anywhere).
Recent v3.16 changes include (see release notes for more):
File export feature added. 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 delimited 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.
