Hello again, Everyone!

I have XP Prof. + SP3

I have just done a routine 'clear' of my temp folder.

I am informed that the one remaining file - Perflib_Perfdata_87c - is not able to be deleted because it is in use by another programme. I do not know how to identify that programme, but I would like to delete the file. As it is in the Temp folder, it is, I believe, deletable without a resultant problem. Please correct me if I am wrong!

1.How may I find out what programme is using this file.
2.How do I find out if the file is important or not.
3.How do I find out what purpose the file has.
4.How do I check what will happen if it is deleted, if it is important - that is if I can find out how to delete it?!

Sorry to put so many questions, but I do not really understand about these files, and I hope that your explanation will make it clearer for me!

Thank you,

Some Temp files are indeed in use by Windows or another program and should not be deleted. Give it a while and in a few weeks or months, try to delete it again. But if you must delete it, restart in Safe Mode and delete it from there. But a word of caution. It may cause problems. Type the file name in Google.

You'll find out if it's important if you have problems when it's deleted. As long as it's in the Recycle Bin it can be restored.

Thank you for your 'wise words' Coryphaeus!

(To take your name literally, I should assume that you are the 'head of the company'!)

I shall leave it alone. It is of no real import, it is only that I was under the impression that all files in the Temp folder were deletable. As this would not delete, I was tempted to think it might be a virus or some such anomaly!

Many thanks, again, I shall close the thread.

Generally, if you can't delete a file it's because it is being used by another program, and so deleting it would be a bad idea.

Also in general, there is no need to clear out the temp folder. Yes, some programs are bad about cleaning up after themselves, but you rarely save any significant amount of space, and the files are otherwise just sitting there not harming anything. The idea that they slow down your system is a total myth.

Jimmy Greystone,

I find that life is great! Being well past my "sell-by" date, I find something to learn each day.

The news about not clearing out the Temp folder is terrific! I have 'religously' emptied it each 3 to 4 weeks because of the 'myth' about slowing down the computer. It can stay there forever, now!

I shall still do a full scan each week with my AVG 8 Free and Spybot -unless you know anything different !! They have been 'good' for me in the past.

Thanks again,

While I see Jimmy's point,

I do regularly clean out temp folders the same as you. I accept they make little difference to performance, but I just feel happier that I am doing the housework, Happy

That perfib_perfdata file you cannot delete is normal. One is created everyday, (or every time the computer is turned on if a day has passed), but after a day you should be able to delete it. It does no harm though.

If you want to get involved with deeper cleaning, you may want to look up and try CCleaner, from

It does temp folders and more. If you do decide to try it, be careful during the install that you watch out for the option to install a Yahoo toolbar. If you don't want it, just say no.

Hello Mark,

Thanks, I will note what you say.

I had C***Cleaner for a short time, but did not fully understand the objects that it 'threw up' and, without realising what I was doing, I deleted some major items that had to be replaced by an "expert" (I know - ex = something that was or has been, and "spert" = a drip under pressure!)But somehow I'd deleted my browser!! - and more....!
