From the developer:
LightDisk is a little application that sits on your system bar, near the clock.
With this application you can forget about checking your disk space, since it will check it automatically for you and will warn you if you are running out of disk space. If needed, the program can even send you and email to you.
You may want to check out more Mac applications, such as Configure Application Dock Tile, UI Browser or Auto Mute, which might be similar to LightDisk.
