I was curious so I ran a little test. I set my system ahead 14 days, and ran the analyze button in CCleaner. Seems CCleaner will clean anything in the prefetch if it has not been accessed in 14 days, including items you routinely use. (see screeny) The items I show only appear after setting my system ahead. So if you are on vacation for a few weeks, come back and run CCleaner, it will most likely empty your entire prefetch folder.

Not entirely correct, when you boot after your holiday elements of pre-fetch will be updated. So not everything will be deleted.

I went into the registry a year or so ago and disabled prefetch. I have not missed it at all. If it does speed up loading it is minimal. I disabled prefetch in an effort to keep my HDD as clean as possible. It appears we are all making much ado about nothing here.

The cleaning of OLD PREFETCH FILES is NOT a DEFAULT setting in CCLEANER.
As I said earlier, you have to check the box, and enable it. After what I've learnt in this thread I won't be "Checking the box" , which as a USER I CHOOSE to do.
Enough about Prefetch for goodness sake Mastertech
The whole point is that it should not be there in the first place and does nothing but slow down application load times.

You have obviously never tested it nor understand how prefetching works. Why would you want to slow down boot and application load times? As clean as possible? LMAO? How?

Only the boot prefetch file will be updated. Everything else will be deleted.

Recently CCleaner has added an internet urban legend as a cleaning option, "Old Prefetch Data". 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.
"Bottom line: You will NOT improve Windows performance by cleaning out the Prefetch folder. You will, in fact, degrade Windows performance by cleaning out the Prefetch folder."
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.
SOURCE
I don't know that I agree that cleaning Prefetch Folder once a month is wrong ??? In fact on this very Forum I've read that It's not a bad thing. I do it ! What's your opinions Evangelist's ?


I am an avid cleaner of Prefetch and it does work. I notice instant change in the performance of my machine. I also run reg scrub, win washer, boot vis, and diskeeper.

It's not funny, because no matter which resolution  you use, you still can see our avatars, right ? If an avatar is too wide like that one up there, all posts  are shifted to far right and people using lower rezolutions will not be able to see the board without constant scrolling left and right...  ;)

No it does not improve performance. Try timing it:

Quote
Testing
Make sure the Task Scheduler service is set to automatic. Launch an application like Firefox three times. Reboot and make sure there is a FIREFOX.EXE-XXXXXXXX.pf file in the C:\WINDOWS\Prefetch folder. If there is, launch Firefox and time it. Then delete the .pf file, reboot, relaunch Firefox and time it again. You will now see Firefox take a significantly longer time to load. Now imagine this on any other application, then imagine doing this deliberately every two weeks? Why? To save a tiny bit of HD space? It makes no sense. 128 .pf files take up maybe 5 MB of disk space.

Cleaning the folder only hurts performance. The reason people think it improves performance is because they do not understand how it works. Please explain how you think it works.

Sometimes it's like that and sometimes it's the way Tim mentioned... I have no clue why, but it looks like forum engine is doing that...
