[[Windows XP Professional monitors the files that are used when the computer
starts and when you start applications. By monitoring these files, Windows
XP Professional can prefetch them. Prefetching data is the process whereby
data that is expected to be requested is read ahead into the cache.
Prefetching boot files and applications decreases the time needed to start
Windows XP Professional and start applications.

Prefetching is further improved if the files are located next to each other
on the outer edge of the disk. Windows XP Professional optimizes the
location of boot files and applications when the computer is idle. The
optimization occurs in the background and lasts only a minute or two; you
might hear the hard disk being accessed when optimization occurs. After the
initial optimization takes place, subsequent optimization occurs, at most,
every three days.

When you run the Disk Defragmenter tools that are included with Windows XP
Professional, they can perform any optimization updates that are scheduled
to take place during the next idle period. The Disk Defragmenter tools do
not disturb the existing layout of optimized boot files and applications.

Note
Computers running Windows XP Home Edition also prefetch and optimize boot
files and applications.]]
