I've been able to deleted files in this foler before but every time I have went to deleted files tonight / morning.

I get the following error message.

Error deleting file or folder can not delete _IU14D2N.TMP-33DAC93E access is denied make sure the disk is not full or write - protected and that the file is not currently in use.

So how can or do I fix this issue.. does any body know ???????.

Thanks a head of time.

Why do you want to delete the files from this folder anyway?

Here's a snippet from taken from the Microsoft website:
"Windows XP monitors the files that are used when the computer starts and when you start applications. By monitoring these files, Windows XP can prefetch them. Prefetching data is the process whereby data that is expected to be requested is read ahead into the cache. Prefetching boot files and applications decreases the time needed to start Windows XP and start applications."

If you disable the PreFetch facility in Windows, it will cause a NEGATIVE impact on performance for most systems. Commonly used applications will take longer to load because you turned off the caching.

Cleaning the pre-fetch folder is not necessary. Windows manages it automatically, dropping out entries that are old or unused. In addition to making your frequently used programs load slower, it will also INCREASE bootup time because Windows has to re-copy all the page files you "cleaned out".

I was once told by clearing the prefetch it would help with the speed of the internet, pc.

So that was why I wanted to do it as I thought it would help my pc out.

I guess I am wrong.
