Blimey,...for ages, was not even aware WizTree could be launched from the CLI...:-(
Thanks for your very useful tip, @TP109 ! ...;-)

For a quick analysis of a specific folder (folder and file sizes, file types, folder size, number of files etc.) use the command line with the name of the folder after the wiztree command, eg., wiztree C:\yourfolder.

After comparing both, WizTree 3 is definitely a lot faster. However, the SpaceSniffer interface updates live as more things are scanned; it's not like you have to wait forever to get feedback. I still enjoy SpaceSniffer's interface and display more; it gives me a much better general idea of where my space is going.

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.

@mcodex:
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

[frmWizTreeMain]
fontsize=8
rowheight=18
showhorizontallines=0
altrowcolors=0
decimalplaces=2

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
windows."

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

@gbrao

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.

WizTree 3.0 released 31-AUG-2017

TPFC 32-bit and 64-bit download links point to the same distribution package:
wiztree_3_00_portable.zip

This package includes two distinct PE's:
• wiztree64.exe
• wiztree.exe

Pick your PE wisely...;-)

Also, note the zip package folder structure has changed from a flat hierarchy in the previous versions,
to a 4-level hierarchy in the current one:

WizTree64.exe
locale
locale\en
locale\en\LC_MESSAGES
locale\en\LC_MESSAGES\default.mo
locale\en\LC_MESSAGES\default.po
locale\How to Translate WizTree.txt
license.txt
WizTree.exe


Lastly, note the developer forgot to update Wiztree's internal version tags:
(from: Sigcheck v2.30 - File version and signature viewer)

c:\wiztree\WizTree.exe:
  Signing date: 2:39 31/08/2017
  Prod version: 1.0.0.0
  File version: 1.0.0.0
  Binary Version: 1.0.0.0

c:\wiztree\WizTree64.exe:
  Signing date: 2:39 31/08/2017
  Prod version: 1.8.0.0
  File version: 1.8.0.0
  Binary Version: 1.8.0.0

There seems to be no going back to other great drive space testers after using this. While others programs on the site have cool visualizations and neat features (two of them listed above in the "Similar apps" area, but the speed with which it analyzes even enormous drives is just too nice.

Also love how it deletes folders (just crossing it out). The only negative (if it's even a negative) is that the directory sizing doesn't change dynamically. So if you go in and manage a few files, the view doesn't change. You have to rescan.

I've used windirstat for years.... but this app is blazing fast. nice find

Very fast launching and scanning. Took about 20 secs to scan 80GB HD in XP.
