What is the main function of disk defragmentation program

The main function of the disk defragmentation program is to defragment some scattered and discontinuous sector space in the disk to improve the read and write speed of the disk. Disk fragmentation refers to discontinuous files generated during the reading and writing process of the hard disk. Disk fragmentation will lengthen the hard drive's seek time and affect system performance.

Detailed introduction:

Disk fragmentation refers to the hard disk fragmentation generated during the reading and writing process of the hard disk Discontinuous files. Non-consecutive writing of files on the hard disk will generate disk fragmentation. Disk fragmentation will lengthen the hard disk's seek time and affect system performance. For example, if virtual memory uses a hard disk, disk fragmentation will occur on the hard disk. Therefore, disk fragmentation will lengthen the hard disk's seek time and affect system performance.

In fact, there should be no doubt about defragmenting the hard drive regularly. If hard disk defragmentation will really damage the hard disk, it will be after the hard disk has been defragmented an almost astronomical number of times. As the hard drive is used for a long time, the file storage location will become fragmented - the file contents will be scattered in different locations on the hard drive.

The existence of these fragmented files will reduce the working efficiency of the hard disk and increase the possibility of data loss and data corruption. The defragmentation program collects these fragments together and stores them as a contiguous whole on the hard drive. Windows comes with such a program: Disk Defragmenter, but there are better such programs in the tool software Norton Utilities and Nuts & Bolts.
