WizTree is a very fast disk space analyzer and search tool, scanning a single folder or your entire hard drive quickly and showing those files and folders using the most disk space. The program uses the NTFS Master File Table (MFT) feature in Windows to rapidly view files.

Note that this high-speed mode is limited to local, NTFS-formatted drives. The program must do a (much slower) scan of FAT-formatted or network drives for analysis.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8 / Win10
Writes settings to: Application folder
Stealth: ? Yes
License: Freeware
How to extract: Download the "Portable" ZIP package and extract to a folder of your choice. Launch WizTree.exe or WizTree64.exe.
Similar/alternative apps: SpaceSniffer, Xinorbis

Looked promising, but wouldn't run at my workplace because, I assume, it assumes that it will be running as Admin in order to peer into the NTFS metadata.

NOTE: SpaceSniffer and WinDirStat does not require Admin.

Yeah I'm not sure what mcodex is smoking, you can like Spacesniffer more because of *reasons, that's subjective, but speed in this case is not. WizTree is damn fast.

I tested spacesniffer on my C: drive (running as administrator) and it took 1m 56s to complete
WizTree's scan took 4.6 seconds (25x faster than SpaceSniffer)

Nice little piece of software. However SpaceSniffer is even better and faster. Link found in Similar/alternative apps. Check it out.

Note that you should close WizTree before making any changes to the WizTree3.ini file as WizTree may overwrite your settings while it's active.

It's possible to tweak the display settings by editing the WizTree3.ini file (located in the same folder as the exe for the portable version)

fontsize = font size used in tree/file views
rowheight = row height used in tree/file views
showhorizontallines = set to 1 to draw horizontal grid lines in tree/file views
altrowcolors = set to 1 to use a gray background for each alternate row in tree/file views
decimalplaces = sets the number of decimal places used when displaying size values in GB/MB/KB. Default is 1

From the dev :
"It's not possible to set the font size at the moment. You could try
using Windows text size scaling to scale everything up on your PC.

The exe doesn't have any dependencies - it should run on any version of

I've e-mailed the dev. Lets see...

Wiztree font size change:
No obvious font parameters selection provided by the developer.

If you feel adventurous, you might want to try your hand at a bit of wiztree.exe plastic surgery, courtesy ResourceHacker ;-)

Is it possible to set the font size ? Bit small for my not-so-young eyes.

Any dependencies ? .NET, VC etc.

Would gladly switch from treesize free to this.
