SpaceSniffer Comments

Works for network drives

Comment by Anamon
about SpaceSniffer Mar 2016

Whereas other disk space usage analysers I've tried had trouble with network drives, SpaceSniffer also supports scanning folders on SMB shares without problems!


I use it all the time

Positive Comment by Anael
about SpaceSniffer Apr 2013

Excellent! Clean, clear, compact.
What I love:
-lets you see the name of the folders AND files.
-different colors for different type of files.
-customisable level of details (how deep in the folder tree you can see).
-option to not display free space on disk.
-auto refresh modified folders.

On the aesthetic side, the initial color scheme was pretty ugly. You can change it very easilly.


Better than others cause...

I love this application. It's fast and I love how it's real time, if a file changes size, is deleted, or otherwise the application instantly adjusts.

about SpaceSniffer and SpaceMonger, WinDirStat Jun 2011

As 72dpi says, a shame more people don't know of it. I much prefer it to both WinDirStat and SpaceMonger, great light-weight tool that can be run from a USB device.


A pity this isn't better known.

A pity this isn't better known. Personally I like SpaceSniffer better than SpaceMonger and the other apps in this category.
