What is defragmentation?
Many users regularly conductdefragment the hard drive in your computer to speed up the system, but not everyone understands what this means. In this article we will describe what is disk defragmentation and why it is needed.
In the NTFS file system, which is used inWindows, files are written to disk in the form of successive fragments - clusters. The larger the file, the longer the sequence of clusters in which it is stored. But with the accumulation of files on the hard disk, there is less space for sequential recording, and fragments of large files are scattered across different parts of the disk. This slows the reading process and shortens the life of the hard drive, as its head is forced to repeatedly move to read the file.
Defragmentation is aimed at assemblingfragments of the file into a single sequence. When defragmented, the data on the disk is distributed so that all the clusters in which one file is recorded are located directly next to each other. For more information about why you need a disk defragmentation, you will read in our article - What is the disk defragmentation for?
If you want to figure out how to performdefragmentation, then you will help the article How to do disk defragmentation. For successful defragmentation, the drive must not be completely clogged, otherwise the system will not have enough free space to redistribute fragments of files.
It is worth noting that defragmentation is not requiredfor all carriers. Since solid state drives and flash drives are designed differently than hard disks, the fragmentation of files on them does not lead to slowing down of work and shortening of service life.
