Does defragmentation help?

yeah ithelps a lot to speed up your computer.As voldrox said it arranges in a proper way and gives more space to fill..To faster the boot,italso depends on the start up applications.If startup applications are less then system boots very fast...

Hi incredible What defragmentation does is rearrange the files on your hard disc properly and accumulate the free space in it, the arranged files makes the computer much more easier to run with... wow 2 years is quiet a long time i have to say, do the defragmentation and certainly you will notice the difference in speed while browsing through folders, do that now... have a nice time here...

Defragging it is long long overdue, specially its a boot drive and even if you still have an adequate free space. The hard disc is the slowest component of a PC that drag PC operation. Although you should feel a speed improvement once you defrag it, there could be other sources that could still slow you down - to many temp/unnecessary files, running unnecessary program at start up and unoptimized registry.

Disk defragmentation is same as cleaning your bedroom. Like your bedroom, software arranges all the data on the hard disk into free space and occupied space. This results in fast boot time as the files of the os are accumalated together by software and so its easy for the os to execute commands faster
