What about Windows XP not completing disk defragmentation

Q: I'm using Windows XP, and when I defragment the C disk, I'm prompted for "C:windowsprefetch Wmiprvse." EXE-28F301A9.PF "The file is corrupted, the scan is not possible, and there is no problem sorting the other partitions, so find a solution."

A: Windows XP uses a "pre-read" technique to load the system and various applications before they are actually used for device drivers, services, and shell programs. The key of pre-read technology is to learn the previous startup process, and to optimize its loading mode for various files to be used during the startup process. This optimization technique is also used on software, which analyzes the first few start-up scenarios for each software and then creates a virtual "memory image" that describes the application requirements and saves the information to the "C:windowsprefetch" folder. Once the image is set up, the software starts up much faster. But the poor prefetching will generate a large number of pre-read files, occupy valuable hard disk space, resulting in system search burden, so that the system runs slowly. After the system has been in use for some time, this read-only folder will become large, which will produce some dead link files, and some even cause some other problems to appear. At this point, just enter the prefetch folder, choose to delete the problem of the dead link file. Generally, do not delete all files in the folder unless there is still an error occurring or there is a problem at startup to recommend emptying the folder.
