There is a folder named c:\windows\prefetch on my system (O.S : Win Xp Home)
It contains a lot of files with the extension .pf:


AGENTSVR.EXE-002E45AB.pf
AVSCHED32.EXE-3A3B77C0.pf
AVWIN.EXE-23715147.pf
A~SOFTU_.EXE-20F81B98.pf
BOULDER.EXE-17C6C09F.pf

etc...


What are the use of those .pf files? Is it possible to delete them safely?

You could rename them to a different extension and see what happens.
Use every app you have for a couple of weeks.

Make sure you have a bootdisk though.

Hi Andrew,

Thanks for your reply, yes renaming can be a solution, but I would like to know why these .pf files are required.

"XP also speeds up and the boot process and optimizes the launch of programs by using prefetching. Windows observes the code and programs that are used immediately upon bootup and creates a list of data to prefetch very early in the boot process. Similarly, as individual programs are launched, Windows keeps track of different files and components are accessed. The next time the application is accessed, Windows prefetches the necessary items to expedite the application's launch. " -quoted from http://www.extremetech.com/print_article/0,3998,a=19543,00.asp
