How to use the Disk Defragmenter in Windows 8

Fragmentation makes your hard disk do extra work that can slow down your computer. Disk Defragmenter rearranges fragmented data so your hard disk can work more efficiently. Disk Defragmenter runs on a schedule, but you can also defragment your hard disk manually.

Option 1 – From Control Panel

 1.      Right click on the bottom left corner and click on control panel.


2.      Then, click on System and Security


3.      Click on Defragment your hard drive under Administrative Tools.


4.      Under Optimize Drives window select the drive you want to defragment, then click Analyze.


 Option 2 – From Command Prompt


1.      Press Win+R key on the keyboard. Under RUN window type cmd and click OK.


2.      In the command prompt window type Defrag.exe and hit enter.


Note: Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.

Option 3 – From System Properties


  1. Open the Windows 8 explorer



2.      Right-click on the hard drive that you think is fragmented and click on Properties


  3. Go to the Tools tab and click on Optimizenow at the bottom:


  Note: The built-in Windows 8 defragmentation program opens. By default, Windows 8 schedules a weekly disk defragmentation. So, even if you have not defragmented your disk, Windows 8 might have done it for you and your disk might not even require a defragmentation.

  1. Select the drive that you want to analyze and click the Analyze button
