SpaceSniffer: freeware disk usage utility

imageMerry Christmas everyone! I  had a fairly unconventional Christmas, spending it with my wife and kid in San Diego (Legoland!) Six hour drive from here, made tolerable by the fact that we have a pretty spacious, comfortable sedan. But I digress. Got back home and did a bit of catching up on the software review sites, and found a program called SpaceSniffer which, amazingly, has within a single hour ousted SpaceMonger as my favourite disk usage analysis tool. I say “amazingly” because I’ve been using SpaceMonger for maybe ten years or more! SpaceSniffer is very similar in functionality and I guess there’s not much separating the two, but the latter does have a bit more configurability in terms of look and feel without appearing to sacrifice speed. Also, while viewing a report of my C: drive, certain directories periodically “flickered” on the screen. I suspect that post-analysis, the program monitors the just-scanned drive and does real-time updates on its display as the contents of directories change. If so, super cool! Lastly, it has an MDI interface, which SpaceMonger does not; this allows you to open more than one window within the program showing the contents of different drives. I’m not sure how often I would use this, but if you need to you can.

SpaceSniffer uses something called “treemaps”, which is a method of visually displaying filesize using boxes of varying sizes. A readout looks a bit messy the first time you see it, but it’s really the perfect way to get an instant idea not only of the largest files on your drive, but also the directories which contain the largest (and most amount of) files. For techies, and simply those people who are anal about space usage and organization, it’s indispensible. I’ve used SpaceMonger many times at work to get a handle on drive usage on one of our big networked file servers so I can hammer people who have been storing backups and other useless crap on it “accidentally”. The program is freeware, which makes it that much more awesome.
