Disk Defragmenter rearranges fragmented data so your disks and drives can work more efficiently. So, we should regularly defragment system hard disk (atleast once per month) to improve system performance. Windows 7 defragment system hard disk on schedule. So you can schedule system defragment in windows 7. In this post, I will show you how to defragment hard disk manually.
- Start >> Type Disk Defragmenter in search box, and then in the list of results, click Disk Defragmenter.
- Under Current status, select the disk you want to defragment and click button “Defragment disk”.
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.
