Space Meter

Space Meter is a feather-light and portable application that lets you study disk space, in order to find the total size of files in any specified directory. It contains only basic options that even first-time users can figure out with ease.

As there is no setup pack included, you can save the app files anywhere on the hard drive or on a removable storage unit, in order to directly run Space Meter on any PC with minimum effort. More importantly, it doesn't make any modifications to the registry, unlike many installers.

The GUI is user-friendly, based on a large window that shows all hard disk drives at startup, including removable and network drives. You can double-click a drive to open its containing folders, select any folder or navigate further, and examine a pie chart shown on the bottom half part of the panel.

This pie chart shows the distribution of the size of all containing files, the current folder, and the remaining directories. There are no other noteworthy aspects available here. Unfortunately, Space Meter doesn't implement options for copying the pie chart to the Clipboard as an image, exporting it to file, or printing it.

It froze a couple of times in our tests while attempting to open network drives. Otherwise, it sometimes took a long time to load drive contents, depending on the drive size. No error dialogs popped up, though.

Sadly, Space Meter has a very light set of options and no configuration settings. There are other disk space managers out there which are also free, such as Disk Pulse, WinDirStat or SpaceSniffer.
