Prefetch from Kelly's Korner

[Prefetch is a new and very useful technique in Windows XP. However, after using XP some time, the
Prefetch directory can get full and have obsolete links in the Prefetch catalog, which can slow down
your computer significantly.
The Prefetcher component in Windows XP is part of the Memory Manager, and helps to shorten the
amount of time it takes to start Windows and programs.
Windows XP "monitors" itself and notices which applications are launched frequently. It gathers
information about these applications and what they access with the launch and stores this
information in the prefetch folder. It then uses this information to "optimize" access to these
files so that they launch faster.
Once every three days, by default, Windows XP will perform a partial defragmentation and adjust the
layout of the disk based upon current use. The files to be moved are written in the file Layout.ini
(found in the Prefetch directory under the System Root directory).]
