Defragmentation is a function that reorganizes fragmented files on a hard disk (HDD) or solid state drive (SSD) into the correct location. You can do this with the free tool “Defragment and Optimize Drives” that is available as standard in Windows 11. The execution time due to defragmentation and optimization may take some time depending on the capacity of the drive and the number of fragmented files. If you are using a laptop computer, we recommend that you run it with the AC adapter connected.
By defragmenting the discs, it may be possible to eliminate the data division state and increase the read / write speed. * Defragmentation is a function to organize scattered data. It is not a function to increase the free disk space.
In this article, we will explain the procedure for executing “Defragment and Optimize Drives” using Windows 11, and how to check the log in the event viewer that allows you to check the defragmentation execution history.
