Jeff Levy has a computer radio show in the L.A. Area. I usually check his lessons every week to see if there is anything I think I can use.

I didn't know what this all meant, but decided to try it. My coupons seems to be loading faster now. So if you want to try it, here are the instructions:

PC LESSON 474
CLEAN OUT THAT PREFETCH FOLDER
One of the things Windows XP gave us was the concept of Prefetch.
Prefetch is the processor action of getting an instruction from memory well before it will need it.
In this way, the processor will not need to wait for the memory to answer its request.
The Prefetch instruction may simply be the next instruction in the program, fetched while the current instruction is being executed. Or, the prefetch may be part of a complex branch prediction where the processor tries to guess the result of a calculation and fetch the right instructions in advance.
The problem with prefetch is that after using it for a period of time, the prefetch folder fills up with junk and obsolete links, and that can slow your XP computer down to a crawl. The solution is to empty the prefetch folder at least once a month. It's easy. Here's how it's done.
Click on Start, Run and type CMD in the box. Press the Enter key or click OK. Now type CDWIND0WSPREFETCH and then press the Enter key.
Now type DEL *.* and press the Enter key. That deletes all of the entries in the Prefetch folder. Type EXIT and press the Enter key to exit back to Windows. That's it - you're done.

I am getting the error "CDWINDOWSPREFETCH is not recognized as an internal or external command, operable program or batch file."

Any suggestions? I am running XP

Not sure if this should be done anyway. I have never heard of Prefetch so I googled it and found some sites saying not to do this. I would think that just defraging would accomplish the same thing. That's what I do.

It looks like you used an "O" whereas the OP had a "0" there, I think. (Old eyes...LOL)

I am very familiar with prefetching at the hardware level in processors, but not really sure with how the O/S uses it.

I thouht how interesting, and went to that link, and good thing I did cuz mrs forgot something real important there. Seems she forgot the back slashes which are important for the DOS commands.



She has:
Click on Start, Run and type CMD in the box. Press the Enter key or click OK. Now type CDWIND0WSPREFETCH and then press the Enter key.

and the instructions on his site are:
Click on Start, Run and type CMD in the box. Press the Enter key or click OK. Now type CD WIND0WS PREFETCH and then press the Enter key.

and YES in windows that is a ZERO not an alpha O.

Thanks Mrs for the hint!

The back slashes disappeared when I entered this here, remove the spaces and put a back slash .

Those two lines/instructions look exactly the same to me. What am I missing?

CD WIND0WS PREFETCH Backslahes should go where I have spaces. For some reason when I submitted the backslashes disappeared.
