Shalom Disk Space is a tool for those people that - like me - enjoy cleaning up their hard disks to get rid of unused files and programs. The idea is that you should be able to know just how much free space you gain by cleaning up. And feel good about it, of course. On the other hand, you can also use Shalom Disk Space to see how much extra space adding files or programs take.
Shalom Disk Space updates its information once a second. And it records the changes in free space in a log file.
