Since defragmentation is a good method to maintain the disk, in this part, we’ll show how to defrag a hard disk in Windows 7 with Windows tools and introduce you to a free defrag tool. How to defragment hard disk in Windows 7? Therefore, the performance of the hard drive will be better, and frequent cleaning of disk fragments will also keep the hard disk in good condition and prolong its service life. This procedure is to rearrange scattered files to decrease searching time. In the end, there are no scattered files on the disk. The disk defragmentation program is to put a large number of scattered files at the end of the disk and then write them into the files associated with it. The intuitive reflection that follows is the system response delay, then the results are the blue screen of death, file loss, and damage, or important data that cannot be repaired When the system is performing file operations, the reading efficiency is greatly reduced due to the repeated search for contact files. Too many fragments are generated, and other discontinuous files increase accordingly. Since the scattered files are continuously stored in contiguous clusters on the disk, the system will add a contact mark between the two segments. How does fragment affect PC/disk performance?

These scattered files are called fragments.Ģ. The meanwhile, users often modify the file, and the new content isn’t added directly to the location of the original file, but the file will be scattered and saved to different places on the disk. However, the working principle of HDD makes it only arrange files discontinuously and disorderly. When you need to boot a program, the disk component will seek all relevant files on the whole disk. In theory, the files should be arranged compactly without gaps and arranged in order of storage time.

Maybe you know that too many installed programs on the disk will cause the low performance of your disk, or insufficient disk space may cause your computer to freeze.īut, do you know disk fragmentation? Do you know that disk fragmentation will not only slow down the system but will also accelerate the physical life of the hard disk and form more bad sectors? Accelerate the physical life?
