What is the use of Disk Cleanup, how to clean the disk? To this problem, here is simple to introduce, in fact, is very simple, the goal is to improve the performance of the hard disk. We know that all the applications in the computer and the system files are placed on the hard disk, so the reading speed is directly related to the reading speed of the hard disk.
Since the hard drive is divided into a cluster, then it is divided into various sectors, file size is different, in the storage system will search the most appropriate size, as time passes between files and files will form some fragments, larger files may also be dispersed storage, resulting in fragments, when reading files need more time and search, Thus slowing down the operating speed, there is some damage to the hard disk, so we usually do a regular disk cleanup.
Disk Cleanup is simple, the simplest of which is from the start-All Programs-attachment-system Tools-Disk Defragmenter tool, and then select the disks you want to clean up, as shown in the following figure:
In addition, it is worth mentioning that the use of a longer computer will produce a variety of system garbage, will also cause slow speed, usually people are accustomed to regular cleaning system garbage, although for the maintenance of systems can help a lot, but ordinary cleaning garbage can not defragment the disk, so cleaning up the disk is a better way to achieve the hard disk acceleration, Therefore it is also a better way to improve the performance of computers.
So as long as we know, the biggest goal of disk Cleanup is to improve the speed of hard disk performance, as well as the hard disk protection has a certain relationship, but do not recommend frequent disk cleanup, too often will have some negative effects on the disk, generally six months to one year or so clean up once is enough.
