Hello, the computer will slow down after a period of use. In addition to system reasons, file fragmentation on the disk is also a cause.

Because the hard disk is clustered first and then divided into sectors, and the file size is different, the system will search for the most corresponding size when storing. Over time, some fragments will be formed between files, and larger files may also be scattered and stored;

After the fragmentation occurs, it takes more time and search to read the file, which slows down the operation speed and does some damage to the hard disk, so it is necessary to defragment it once in a while;

Disk defragmentation method is as follows:

1, click "Start-All Programs-Accessories-System Tools-Disk Defragmenter", and pay attention to the steps;

2. After entering, click the "Fragmentation" button to start defragmenting disk C:

3, the first finishing time is longer, and the speed will be much faster in the future;

4. The red part below is fragment, the blue part is sorting file, and the green part is system file;

5. To defragment other disks, you can select it and click "Defragment";
