Specs: Microsoft Windows XP Professional, 3.416 GHz / 1023 MB
Someone suggested to me to type the above mentioned commands in Run & then to delete all files in theses folder. Deleting all files in these three folder is good for the copmuter & makes it run faster, she says. Is it true or False?

It depends on who you ask. Probably depends on what you are trying to do.

As I understand Prefetch, it's intent is to speed things up, but like other things in Windows, it is reported to possess the strange power of slowing things down.

I've heard advice both ways and have chosen to leave it alone because it rebuilds the content over time. Meaning that you might get short term results only.

Present your question on google search & see what you come up with. I checked mine just now, content approx 2.58mb, hardly worth thinking about.

Info at link below. Different slant than I've seen before. Modifying it seems mor reasonable than deleting it's contents.

There is nothing to learn from someone who already agrees with you.

Ccleaner seems to do a good job with some of the others with less hassle

I have the programme, it does not clean the three mentioned folders. Regarding the size; the 2nd temp folder's size in my pc is over 500 mg, what do you advice guys?

Just don't mess with the Prefetch folder. it will not provide any increase in perormance, exactly the opposite. Also be sure Task Scheduler in Services is set to Automatic and started.

I tested clearing Prefetch folder. You will not like the results. Changing registry values produces nothing positive.

your call on the others.

Leave Prefetch alone - XP manages it and periodically prunes the files therein. In any case, the files are quite small. DO clean out your temporary folders regularly - it's amazing what get's left in there. I use Empty Temp Folders (Freeware) to clean these and other folders like Firefox's Cache. There's no performance advantage as such, but I don't like lots of useless old junk clogging up my drives (MS Office excepted).

A regular defrag WILL help disk performance - but clean out the junk first, and emptying Temporary Internet Files every couple of weeks is also a good idea - make sure the limit is set to something reasonable like 50Mb or 100Mb (see Internet Options in Control Panel). In these days of high-speed broadband it's silly to have IE taking longer to search for a web-page item in the TIF cache than to download it afresh. I've seen one case where someone was considering buying a new computer because Internet access had slowed to a crawl. Their TIF limit was set at 1500Mb - there were over 100,000 files in there, which took over 20 mins. to delete. Result - the snail turned into a hare.

The system only looks for a prefetch file when a program starts. If there
are redundant ones around for a while they are ignored, so there will be
no loss of performance.

When there are 130 or so their number is reduced autotmatically by Windows to the lower 30's, all of them being programs that are currently present and the most recently used. As their number builds quite quickly this purging will usually happen every few days (depending upon usage).

Pruning them is therefore a pointless waste of time. If you delete the
lot, programs will initially start more slowly. MS did not put them in the system to impair performance, quite the reverse.

Someone who didn't understand Prefetch started this deletion myth and it then got copied all over the web. Forget it.

some other bloke...

Omda, you say you have CCleaner. My guess is you simply need to check a few things in it and run it periodically. I'd leave prefetch alone, but the rest are valid.
A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner can get rid of it when it’s ticked (not to worry, it gets rebuilt EMPTY on the next boot.).
