Cleaning the Prefetch folder is an internet myth
that simply will not die due to the gross ignorance of many people in
regards to how Windows XP Prefetching works. These same people generally
recommend other bogus advice such as disabling Windows Prefetching
completely and adding /Prefetch:1 to desktop shortcuts.

CCleaner for the most part is a good application,
it quickly and easily removes temporary and unused files from Windows.
It has a nice interface that clearly shows what has been "cleaned". On
neglected systems this can free hundreds of Megabytes of harddisk space.
Apparently in the authors quest to clean everything and anything, he
blindly ignored how Prefetching works.

Prefetching Facts
1. Prefetching is enabled by default in Windows XP.
2. Prefetching is configured optimally by default.
3. Prefetching will significantly improve application load times.
4. The Prefetch (.pf) files are not a cache, they are reference files.
5. The Prefetch (.pf) files do not preload/cache anything upon Windows startup that does not normally load at startup.
6. Only one Prefetch (.pf) file is referenced during startup = NTOSBOOT-B00DFAAD.PF
7. Only one Prefetch (.pf) file is created per application.
8. The Prefetch (.pf) files including the Layout.ini and NTOSBOOT-B00DFAAD.PF files are automatically updated.
9. The Prefetch folder is auto cleaned after 128 entries have been reached down to the 32 most used applications.
10. Notebooks running on battery power will not execute idle tasks and thus cannot further optimize or remove prefetch files.

Conclusion
Do not clean the prefetch folder! If you use CCleaner uncheck the "Old Prefetch data" option. Finally let the makers of [You must be registered and logged in to see this link.] know they need to remove this option from CCleaner!

Thanks For Reading Comrades .

Well, old prefetch considered as a junk file that's why everyday i delete it.

@starcraft

I have updated my post Smile

and I guess haggling on this matter by assumptions and myth
wont improve the discussion.

I guess my references and official statement from microsoft would be enough to explain the facts.

Its consider as that. You try to read it. Prefetch is a Windows folder that contains shortcuts to certain programs used frequently to aid in their quicker startup. Emptying that folder is not harmful, in fact it is a common thing to do in removing malware. Whatever you do do not use the reg cleaner in ccleaner. It can and has hosed a few systems I was working on in the past before I knew it was there.
