Defragmentation is the process in which fragmentation is reduced. It is a vital importance in the performance of your computer (unless you have an operating system like Ubuntu, in which case don't worry about it). This tutorial will explain the details and important tips of defragging your hard drive.
Why do we need to defrag?
Defragging your hard drive is vital because it reduces the amount of fragmentation by physically organizing the contents of the mass storage device, thus effectively speeding up performance and freeing up disk space. If you don't defrag your hard drive, there could be dire consequences.
When do I need to defrag?
It is best to usually defrag your hard drive at least once a month or every two months. Of course, you can defrag when you get around to it as well.
How long does it take to defrag?
The amount of time it takes to defrag your hard drive usually depends on the amount of space currently available and the overall performance of your compuer. If you have a fast computer, time is usually short. But an important thing to remember is when your defragging, do not do anything on the computer other than let it defrag. Not doing so will interrupt the process.
