Manage pre-read files for Windows XP/2003

In order to improve the performance of the system and speed up the system startup and file reading speed, the pre-reading function has been added in Windows XP/Server 2003. The Windows\\Prefetch folder under the Windows XP/Server 2003 system disk is the pre-read folder, and there are many files with the PF extension in the Prefetch folder. This is the pre-read file generated by the system. However, if this function is not used well, it will generate a large number of pre-read files for a long time, occupying valuable hard disk space, causing the system search to take longer, increasing the burden of system search and making the system run slower. Therefore, only by properly managing and using these pre-read files can the system performance be optimized and the system run faster and smoother.

First let us create a pre-reading method that suits you. By default, Windows XP/Server 2003 only pre-reads Windows system files. For those who don't have a high computer configuration, they may want to cancel the pre-reading function. For a friend with a high computer configuration, they may want to pre-read some files. How can we create a pre-reading method suitable for you?

In fact, Windows XP/Server 2003 allows us to change the pre-reading method and set the pre-read object by ourselves. To do this, click on "Start → Run", type "Regedit" in the Run dialog box, open the Registry Editor, expand the HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\PrefetchParameters branch, and find the right window. The "EnablePrefetcher" is the pre-reading method of Windows XP/Server 2003 controlled by this key value. Double-click on "EnablePrefetcher" to open the "DWord" value editing window and pre-read the Windows XP/Server 2003 by changing the value of "Value Data".

Set the "Value Data" to:

"0" - cancel the pre-read function;

"1" - the system will only pre-read the application ;

"2" - the system will only pre-read Windows system files, this is the default setting of Windows XP/Server 2003;

"3" - the system will pre-read Windows System files and applications.

Okay, now you can define your own pre-reading method according to your computer configuration.

Second, we have to develop a good habit of regularly cleaning up pre-read files. You can manually delete all the files in the Prefetch folder at intervals. In this way, the pre-reading function of the system can serve us better
