How to avoid and clear disk fragmentation in Linux systems

Linux system is a widely used operating system, which has many advantages, such as stability, security, efficiency, etc. However, the Linux system is not perfect, it will also face some problems, one of which is disk fragmentation. Disk fragmentation means that the data blocks of files in the file system are scattered in different locations on the disk, resulting in reduced reading and writing efficiency and even affecting system performance and stability. So, why does disk fragmentation occur in Linux systems? How to effectively avoid and clear disk fragmentation? This article will answer these questions for you and provide some practical methods and techniques.

Benefits of disk defragmentation

1. Disk defragmentation can make the system run more smoothly, reduce lags, and improve system performance.
2. It should be noted that users who use solid-state drives must not use the "disk defragmentation" function. Because the technologies used are different, using the disk defragmentation that comes with Windows will greatly shorten the life of the solid-state drive.

Methods and steps for disk defragmentation

Open "This PC", select any disk drive letter, and then click "Manage" - "Optimize"

Select the defragmented disk, you can use "Ctrl" and "left mouse button" to select multiple disks, then click "Optimize" and wait patiently for the defragmentation to complete.

Now that you know the benefits of disk defragmentation, it is best to develop the habit of regularly defragmenting disks.

Through this article, we learned about the causes and harms of disk fragmentation in Linux systems, as well as how to check, prevent and defragment disk fragmentation. We know that due to the use of a log file system in the Linux system, the generation rate of disk fragmentation is relatively low, but this does not mean that it can be ignored. We should regularly monitor disk usage and try to avoid low disk space or excessive partitioning to reduce the possibility of disk fragmentation. If we find that the disk fragmentation rate is too high, we can copy files, format partitions, or use tools such as e4defrag to defragment the disk. Of course, before performing any operation that may affect files or data, we must make a backup to prevent accidents.
