History
Features
SpaceSniffer comes in a single edition that runs on the Windows operating platform.[2] The actual version comes only in 64-bit, although the homepage states that it runs on Windows 2000 and higher. A few older versions are available on the download page. The executable file can be simply copied without requiring any other installation process.[3]
It is free for all uses, but donations are suggested.[2] No source code is available.
Notable features include:
- A treemap represents how disk capacity is allocated.[4]
- Filters (based on file name, age, size, etc.) enable the user to focus the visualisation on files and folders of interest.[4]
- User-chosen colours can be associated to different file types.[5]
- NTFS Alternate Data Streams are supported.[5]
- commandline usage (non-graphical, console usage)
Reception
The application has been reviewed favourably by editors and users.[3][5] PCWorld concluded its review by pronouncing it a “recommended download”[2] and Freewaregenius.com called it “a very well made program that is simple, intuitive, elegant, and very useful”.[4]
Reviewers and users have noted that the treemap presentation “can be a bit overwhelming at times” or “cluttered and more complex than necessary” but concluded that it was “effective”.[3]
