Even there is not any virus in your computer, it still cannot work fast as before, why? If you are an experienced computer user, it does not seem difficult for you, because you can defragment disks when the computer is becoming slow. It is really a good method to optimize computer performance.
Well in this article, I will tell you the main causes of disk fragments in a hope that it can help you prevent the disk fragments in advance.

The major cause should be blamed for the virtual memory programs. If there is not enough physical memory to run the application, the operating system can produce temporary swap files in the hard disks. Such file virtualizes the hard disk space as memory so its program can do massive read-write operations to the disk and create fragments. At the same time, during operating the files such as moving or deleting, Windows system may apply virtual memory to manage applications synchronically which may lead to the frequent read-write operations of every program to hard disks. This is another main resource of disk fragments.

What is more, if any sector is removed and then the system reads a new and smaller file into it, there may be some empty space beside this file. And if the system continues to write more files into this disk, the space between those two files can not put any new one any more. That is to say, the file has to be divided into several parts in order to put in the disk. See, file fragments are produces again.

If you are a movie fan and like to download from Internet, you have to pay close attention to the disk fragment problem. Once you are doing other operations during the downloading process, the film files are forced to separate into certain fragments and restore in the disk. So, downloading is one of the main causes of disk fragments. Besides, if file space is not large enough to support the frequent deleting and adding files operations, it can bring about a huge number of disk fragments as well. Such problem can go from bad to worse on the condition that you do that hourly.

Generally speaking, sometimes you may not be aware that when browsing websites or playing games, it can produce a mass of temporary files in the computer. Or when downloading video in your hard disks, it is easy to produce a lot of disk fragments. If you find computer performance is not so good as before, I suggest you to defragment disk firstly.

When performing defragmentation, please close down screen saver and do not do anything else in the computer such as listening music or playing game but just let defragmenting program run by itself. By doing this, you can not only speed up defragmenting speed but also prevent the program from starting again and again.

In order to facilitate the speed of defragmentation, you can also use certain defrag to help you. By using it, you can also protect your computer from any unexpected accidents during defragmentation.
