The Open Files sensor has detected a large number of open files. Many files open concurrently can degrade system performance.
Close any non-essential applications. They may be using many dynamic link libraries (DLLs), which add to the number of open files and remain open as long as the applications are running.
The trigger level for this sensor's alarm determines what Norton System Doctor considers a "large" number of files. To change the trigger level, click Change Alarm Settings.
