This article will explain in detail why disk defragmentation is not needed in linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The vast majority of computer users are using the windows system, we all know that when the computer is very slow, one of the ways is disk defragmentation, but in the linux system, there is no disk defragmentation function, why not need disk defragmentation in linux?

This is due to the fact that the file systems of linux and windows work differently.

Defragmentation is to reduce the precision of fragmentation by moving files, so that files can be stored continuously on the hard disk as far as possible.

There will always be fragments in the file system of the windows system when saving files, while linux takes a more intelligent way to place files, it scatters files across the disk, and files have a lot of free space directly. Even if they produce fragments, the file system will move files in daily use to reduce fragmentation, without the need for a special defragmenter.

What if I want to defragment the linux system? That requires copying all the files, then emptying the partition, and then copying the files back.

A method for detecting the degree of linux fragmentation: look at the number of discontinuous I nodes (non-contiguous inodes) in the output
