Analysis of the use of cleaning computer disk

        Recently, some netizens asked Xiaobian, what is the use of disk cleaning? In response to this problem, here is simple to introduce to you, in fact, very simple, the purpose is to improve the performance of the hard disk. We know that all applications and system files on the computer are placed on the hard disk, so the reading speed is directly related to the reading speed of the hard disk. Since the hard disk is divided into clusters, and then the headers are divided into sectors, the size of the files is different. When storing, the system searches for the most corresponding size. Over time, some fragments are formed between the files and the files, and larger files are also formed. It may be distributed and stored. After fragmentation, it takes more time and search to read the file, which slows down the operation and damages the hard disk. Therefore, we usually perform disk cleaning periodically. Disk cleaning is very simple, the simplest is from the "Start - All Programs - Accessories - System Tools - Disk Defragmentation Tool", and then select the disk that needs to be cleaned, as shown below: Win7 disk cleaning is also worth mentioning, Using a longer computer will produce a variety of system garbage, which will also cause slower speed. Usually people are used to cleaning up system garbage regularly. Although it helps a lot to maintain system performance, ordinary cleaning garbage can't defragment the disk, so clean the disk. It is a better way to achieve hard disk acceleration, so it is also a preferred method to improve the performance of the computer. Therefore, we only need to know that the biggest purpose of disk cleaning is to improve the performance of the hard disk. In addition, it also has a certain relationship with the hard disk protection. However, it is not recommended to perform disk cleaning frequently. Too often, it will have some negative impact on the disk. Generally, it will be cleaned for half a year or a year. One time is enough.
