How to defrag your computer and why Defrag

Computer defragmentation. Also known by the name of defrag, it is important that you know how to defrag your computer and why you do it.

What Is Fragmentation?

You know that files are stored on your hard disk. When old files are deleted, this leaves behind empty spaces equal to the size of the deleted file. When we are writing a new a file to the hard disk, the Operating System checks the hard disk for empty spaces in which to insert the new file. If the closest empty space is not large enough to hold the new file, the operating system will break the file in to small pieces (called fragments) which will be inserted in to the available empty spaces.

This process is known as fragmentation. As time goes by, there will be a lot of fragmentation on your hard disk as more and more files get deleted and stored. However, it takes longer to access these fragmented files as they are stored in different locations on the hard disk. The hard disk heads which read the file will have to travel from one location to another to manage to read the whole file, and this takes more time than normal, slowing down your computer. Therefore it is important to remove fragmentation from your computer whenever possible.

How to Defragment Your Hard Drive

Windows has a handy in-built tool that can be used to defragment your computer: the Disk Defragmenter. This can be found by going to the Start Menu->Accessories->System Tools->Disk Defragmenter.

It allows you to choose a drive on your hard disk and defragment it. The disk defragmenter searches through the hard disk for fragmented files and brings all those fragments together to a single location so that those files may be read faster. This allows your computer to run more efficiently as files are being read faster.

Now that you know how to defrag your computer and why you do it, you can speed up your computer considerably.
