WizTree is a tool that helps Windows users find large files and folders on their computers. It scans a drive and shows which files use the most space. This helps users understand why their hard drive or SSD is running out of space.
WizTree is known for its fast scanning on NTFS drives. It also uses a visual chart to show how storage space is being used.
In this review, we will explain WizTree’s features, speed, safety, pricing, limits, and alternatives.
What Is WizTree?
WizTree is a disk space analyzer. It shows how much space files and folders use on your computer. It helps you find large files without opening every folder yourself.
For example, your computer may show a low disk space warning. You may not know what is taking up all the space. WizTree scans the drive and shows the largest files and folders.
It also has a colored chart called a treemap. Each rectangle represents a file. Large files appear as large blocks, while small files appear as small blocks.
This makes it easier to find large videos, backups, old downloads, and other files.
WizTree is developed by Antibody Software and is mainly made for Windows computers. One collected source also mentions a separate Mac application, but its current availability has not been confirmed.
WizTree does not clean your computer automatically. It helps you find files, but you must decide which ones are safe to delete.
How Does WizTree Work?
WizTree uses different methods to scan drives. Its main speed advantage comes from how it scans NTFS drives.
What Is the Master File Table?
The Master File Table (MFT) is part of the NTFS file system used by Windows. It stores information about files and folders on a drive.
WizTree reads this information to find file names, locations, and sizes. This can be much faster than checking every folder and file separately.
Direct MFT scanning requires administrator permission. This is why WizTree may ask you to allow administrator access.
Why Is WizTree So Fast?
Many disk analyzers check folders and files one by one. WizTree can read the MFT directly on NTFS drives.
It also keeps scanned information in memory. This helps it sort files and show results quickly without scanning the whole drive again for every action.
One article reports that WizTree scanned a 1 TB hard drive in about 11 seconds. This was one user’s test, so your results may be different.
Scanning speed depends on your drive, computer, file system, and number of files.
Does WizTree Work on Every File System?
WizTree can scan different types of drives, but the speed may vary.
- NTFS: Supports direct MFT scanning and is usually the fastest option.
- FAT32 and exFAT: May take longer because a different scanning method is used.
- Network drives: Speed depends on the network connection and setup.
WizTree may scan one drive in seconds but take longer on another.
WizTree Main Features
WizTree has several features that help users understand how their storage is being used.
Folder Tree
The folder tree shows files and folders in an organized list. It helps you find which folders use the most space.
You can open folders, view their contents, and sort the results. This makes it easier to find large folders on your drive.
Treemap Visualization
The treemap shows files as colored rectangles based on their size.
Large files appear as large blocks, while small files appear as small blocks. Different colors help you tell file types apart.
You can click the blocks to explore files and folders. This helps you find large videos, backups, and other files without opening every folder manually.
Largest Files List
WizTree can show the largest files found during a scan. This helps you focus on files that use the most space.
For example, you may find an old backup, a large video, or an installer you no longer need.
Always check a file before deleting it. Some large files are important for Windows or other programs.
File Search and Sorting
WizTree lets you search, filter, and sort scan results. These tools help you find files and check their details.
You can sort information such as file size, storage percentage, file count, and modification date, depending on the available columns.
You can also open a file’s location in Windows Explorer or copy its path. This helps you check the file before removing it.
Duplicate File Finder
One collected source reports that WizTree version 4 introduced a duplicate file finder.
This feature helps you find files that may be stored more than once. Removing unwanted copies can free up space.
However, files with the same name are not always identical. Some duplicate files may also be needed by different programs. Check them before deleting anything.
CSV Export
The collected source also reports that WizTree can export file information to a CSV file.
You can open a CSV file in a spreadsheet program. This is useful when you want to sort the results, review disk usage, or save a record of your scan.
File Management
WizTree lets you work with files from its results screen. Depending on the file, you may be able to open it, copy its path, or delete it.
These options make it easier to manage files without searching through folders yourself.
However, WizTree cannot know which personal files you want to keep. Always check a file before deleting it.
How Fast Is WizTree?
WizTree is especially fast on NTFS drives because it can read the Master File Table directly.
One article reports that it scanned a 1 TB hard drive in about 11 seconds. This was one user’s result, not a guaranteed speed for every computer.
The collected review also mentions an older test that claimed WizTree was 46 times faster than WinDirStat. However, the test used an old version of WinDirStat, so it may not show how the current versions compare.
Newer versions of WinDirStat are also reported to support direct NTFS scanning. This means older speed tests may no longer give a fair comparison.
Your results will depend on the drive, its speed, the number of files, and the scanning method.
WizTree can be a fast way to check NTFS drives, but one test cannot show how it will perform on every computer.
How to Use WizTree to Find Large Files
Using WizTree is simple. Follow these steps to check your drive.
Step 1: Download WizTree
Visit the official website at diskanalyzer.com. Choose the installer or portable ZIP version if available.
Downloading from the official website helps reduce the risk of getting an unwanted or changed version.
Step 2: Open the Program
Install WizTree or open the portable version. You may need to allow administrator access for fast MFT scanning.
Step 3: Select a Drive
Choose the drive you want to check, such as C:. Click the scan button to start.
Step 4: Check the Results
When the scan finishes, look at the largest files list and folder tree. Use the treemap to find large files quickly.
You can open folders and check file paths to understand what is using your storage.
Step 5: Check Files Before Deleting Them
If you find a file you no longer need, open its location or check its details first.
Do not delete unknown system files just because they are large. If you do not know what a file does, leave it alone until you can confirm its purpose.
Step 6: Scan Again
After deleting files you no longer need, scan the drive again. This helps you check the results and see how much space you have freed.
Is WizTree Safe to Use?
The sources collected for this review describe WizTree as a legitimate program developed by Antibody Software.
For safer use, download it from the official website: diskanalyzer.com. Avoid unknown websites that may provide changed files or unwanted software.
WizTree may ask for administrator permission because it needs access to the NTFS file system for fast scanning.
The main risk comes from deleting files without knowing what they do. WizTree helps you find large files, but it cannot decide which files you need.
Check a file’s name, location, and purpose before deleting it. If you are unsure about a file, leave it alone until you know it is safe to remove.
What Should You Avoid Deleting with WizTree?
Not every large file is unnecessary. Some files are needed for Windows, programs, or games to work properly.
Be careful with these files and folders:
C:\Windows: Contains important Windows files. Deleting them can cause system problems.pagefile.sys: Helps Windows manage memory when physical RAM is not enough.hiberfil.sys: Supports Windows hibernation.AppData: May contain program settings and saved information.- Game folders: May contain game files, saved data, and settings.
If a program uses too much space, try clearing its cache through its own settings. If you no longer need a game or program, uninstall it through Windows Settings or its official launcher.
You can also use Windows Storage settings and built-in cleanup tools to remove supported temporary files. These options are safer than manually deleting files you do not understand.
Is WizTree Free? Pricing and Licensing
WizTree is reported to be free for personal use. However, businesses generally need a paid license.
The collected sources mention these licensing options:
- Personal use: Free for non-commercial use.
- Commercial use: Requires a suitable paid license or Supporter Code.
- Enterprise use: A separate license may be available for larger businesses.
- Distribution: A separate license is mentioned for sharing WizTree or including it in another application.
One source reports that commercial licenses start at around $25 for an individual or small organization. This is a reported figure, not a confirmed current price.
Prices and license rules can change. Check the official WizTree website before using the software for business.
Free personal use does not automatically mean free business use.

Common WizTree Problems and Troubleshooting
Why Is WizTree Scanning Slowly?
The speed depends on your drive and file system. NTFS drives can benefit from direct MFT scanning, while FAT32, exFAT, and network drives may take longer.
Check your drive’s file system and give the scan time to finish.
Why Does WizTree Ask for Administrator Permission?
WizTree needs administrator access to read the NTFS Master File Table directly. This helps it scan supported drives quickly.
Why Is My Drive Still Full After Deleting Files?
Scan the drive again to update the results. Also check the Recycle Bin because deleted files may still take up space until they are permanently removed.
Check the files inside the Recycle Bin before emptying it.
How Do I Identify an Unknown Large File?
Check the file name, folder location, and properties. Look up the file if you need more information.
Do not delete an unknown file just because it is large. It may belong to Windows or an installed program.
Why Are Windows Folders So Large?
Windows stores system files, updates, temporary files, and other data on your drive. Some of these files are needed for your computer to work.
Use Windows Storage settings or built-in cleanup tools to remove supported unnecessary files. Avoid manually deleting unknown files from system folders.
