A little context goes a long way.

General definition - Data is pre-fetched in anticipation of what the computer thinks you/the program may need next - without waiting until you/the program asks for it. Then it's available to you/the program faster.

It's the method used by XP Pro Windows XP to monitor files that used at startup and when applications are started.

Whilst monitoring these files, Windows XP Pro can prefetch data expected to be requested. and read ahead into the cache.

Prefetching boot files and applications decreases the time needed to start Windows XP Pro and open applications.

I used a small file which optimises the prefetch sequence; it can be downloaded from:

Pre-fetching is a technique used throughout computers - inside the processor - inside hard drives - literally everywhere.

"Prefetching boot files and applications decreases the time needed to start Windows XP Pro and open applications."

The only reason the PC speeds up is because the PC isn't sorting the Prefetch data. However with no Prefetch data the PC won't be as optimised as if you leave it alone.

Geedad - i can't see the program listed on the first link but the second one takes you striaght to it.

Oooppss - not enough coffee yet...

The only reason the PC BOOT UP TIME speeds up is because the PC isn't sorting the Prefetch data.

However with no Prefetch data the PC won't be as optimised DURING DAY TO DAY USEAGE as if you leave it alone.

I use the first one and it's configured to defragment at every boot - it does appear to speed things up but, of course, it may be an illusion...:-)

Website is at:

and you can also (obviously) download it from the same website as well as find a description of what it does:
