Optimization rearranges file fragments into adjacent
or contiguous clusters. When the drive head accesses
all of the file data in one location, the file is read into
the memory faster. Optimization also maximizes the
usable free space on a disk by grouping most frequently
used files and infrequently used files. Optimization
consolidates free space to avoid fragmenting newly
added files. It adds extra space after major data
structures so that they can grow without immediately
becoming fragmented again.
You can optimize your boot volume manually by using
the Optimize option in the Performance window.
You can also configure Norton Internet Security to
defragment your boot volume or the local disk that
contains boot volume when your computer is idle.
Norton Internet Security automatically schedules the
optimization when it detects the installation of an
application on your computer. The optimization
process starts next time when your computer is idle.
You can use the IdleTimeOptimizer option to optimize
the boot volume during the idle time. To access the
Idle Time Optimizer option, go to the Norton Internet
Security main window, and then click Settings >
General > Norton Tasks > Idle Time Optimizer.
Optimizing your boot volume
The Optimize option lets you optimize your boot
volume to improve the boot time of your computer.
Optimization of your boot volume maximizes the usable
free space by rearranging file fragments into adjacent
and contiguous clusters. When the drive head of your
hard disk accesses all of the file data in one location,
the file is read into the memory faster.
When you use the Optimize option in Windows XP,
Norton Internet Security optimizes only the boot
volume (for example, C:\Windows). Therefore, it
requires less time to complete optimization. However,
when you use the Optimize option in Windows Vista
or Windows 7, Norton Internet Security optimizes the
