Ximinez is a disk usage analyzer and comparator. It enables you to take snapshots of disk usage for a given folder, to browse through the snapshots, and to view differences between snapshots. It is aimed towards solving problems like: "Why is my disk suddenly so full when it was OK just recently?" Besides the GUI, the package also includes an optional command line tool, which can be used, for example, in conjunction with a scheduler to take snapshots on a regular basis.
