Unlike the low-disk space notification built into some of the Windows operating systems, Space Patrol provides a low-disk space monitoring and notification facility that you can control precisely.
Space Patrol lets you alter the threshold levels, and easily enable or disable the notification on any of your disk drives. Once you've registered your saved settings are automatically monitored whenever you log onto your computer.
Features
* Displays all relevant disk drive information.
* Simple operation.
* Allows you to disable your Operating System's low-space notification facility.
* Works for all users on your computer (NT/2000/XP/Vista).
Until you've registered Space Patrol your saved settings are not automatically applied when you log on - but you can easily reapply them in order to evaluate the product.
