Linux only: We've seen how visualizing your hard drive usage can help you clear the biggest space-eaters and make room for more useful information, and KDE-based Linux users have a great tool to do that. Free download Filelight scans your hard drive and displays space usage on a colored radial, with details that pop up as you mouse over each segment. Directories closest to the system root are show on the inside, and Filelight seems to have few problems analysing mounted non-Linux-format partitions, such as Windows. For those who liked the looks of Baobob but try to operate in a clean KDE environment, Filelight is an attractive space-making tool. Filelight is a free download for Linux systems only.
