Disk Defragmenter

What is Disk Defragmenter?

Disk defragmenter (also called disk defrag) is a program that is designed to optimize disk access and improve computer performance. It does this by grouping corresponding pieces of data together. This reduces the time the computer needs to search for the next necessary piece of information.

Why Should I use Disk Defragmenter?

Imagine a library so busy that when new books came in, the librarian barely had time to find room to store them, much less put them in their proper place. At the same time, removing old unwanted books left gaps in the shelves because there was no time to re-organize. Eventually books would end up in any spot that will hold them, regardless of whether they were in the correct section or even alphabatized. This would ultimately result in complete chaos and slowdown in library services.

This is the exact same thing that happens to your computer every time you turn it on. Every program we use and every button we click causes the computer to send and retrieve data. Because the computer is so busy doing what we ask, it doesn't have time to stop and re-organize on it's own. Instead, it just places data wherever space is available in order to keep up with the demands of the user. Over time, this data gets more and more disorganzied and can cause your computer to slow down.

Because of this, the computer relies on us to choose when to stop and defrag (re-organize) our hard drive.

When Should I Use Disk Defragmenter?

Ideally, it would be best to run it on a weekly or monthly basis. The more often you run it, the less time it takes to re-organize your data.

How Do I Run Disk Defragmenter?

Open My Computer, right click on your hard drive (C:), click on properties, click the Tools tab, and then click on Defragment Now.

Please note that running disk defragmenter can take anywhere from several minutes to over an hour. It is best to do this when you are not planning to use the computer for an extended period of time. It is also recommended that you temporarily disable your screensaver before starting the program.
