The Disk Space sensor has detected a low amount of available space on a disk.
Free up some disk space to avoid problems while running applications, creating, or copying files. To free up disk space, delete unnecessary files, compress infrequently used files, or move some files to another drive that has more space.
The trigger level for this sensor's alarm determines what Norton System Doctor considers a "low" amount of space. To change the trigger level, click Change Alarm Settings.
