Defragmenting your computer's hard drive can allow it to regain a second youth and gain in performance. We explain how to do this.

Expertsconnecting helps you learn how to configure and secure Windows 10. It is indeed important to start on a good footing with an operating system that we use every day, often for both professional and personal needs.

Why defragment your hard drive?

A computer's hard drive is divided into sectors, and it's the OS's job to put them together to form blocks (also called clusters). But the more a computer is used, the more the writing of files on the hard disk tends to scatter all over the storage space. It then takes longer to access the files, because the system must scan the entire hard drive to reconstitute the sets of elements. The deletion of files or the action of software in the background also contribute to this phenomenon of fragmentation, which slows down the PC.

This is where defragmentation comes in. Know that this technique was very useful in the past to give a boost to your computer. Today, Microsoft has improved its operating system and fragmentation does less damage than it once did, thanks in particular to automatic processing tools. But it is still possible to perform such an operation manually, which Windows now prefers to call "optimization".

Defrag your hard drive

Follow the steps below to defragment your computer's hard drive in Windows 10:

  1. Launch File Explorer. In principle, a shortcut to this window is available by default directly from the taskbar.



  2. Right-click on the hard drive you want to defragment and select "Manufacturing ".

  3. Click on the "Tools".

  4. In the section "Optimize and defragment the drive", Click on the button "Optimize their campaigns".

  5. Select the drive to optimize again from the list and press "Optimize their campaigns" one last time to start the process.


And now, voila ! Depending on the size of your hard disk and the number of files present, the duration of the operation can be very variable. Do not panic if it takes several hours, the procedure can be long. Note that with the Windows 10 Scheduled Optimization tool, your PC can launch a defragmentation alone at the frequency of your choice (every week for example). Then you won't even realize when Windows will perform an optimization of the disk(s).
