One of the most unused tasks in windows is certainly defregmentation. Rare are those who use this weekly or even daily. I’m more among those who are more rarely running this tool, usually when the computer starts running slovely or when large amounts of files were moved.

For those who have never heard for disk defregmentation before or use it; it’s like cleaning your closet. It’s amazing how quickly I can found my favorit T-shirt after that. And that’s like it with computer. Application founds messed/fragmented files all over the disk and than stacked together. This speed up the computer at startup and during operations.
