    Defragmentation for Linux is a heresy, be careful, Linux fanboys might overreact if you ask them about it. 😉
    Win XP had a decent graphical built in tool to do the same. I remember the old Auslogic 4.5 was good.

      Hi Alex,

      Thank you for your comment. We agree with you, Windows XP had a pretty graphical inbuilt tool for defragmentation. Also, it exists in the existing Windows version too. But using a defrag tool makes the task easier, accurate and can be done faster.
