Do you have any idea about Defragment?
Well, Everytime when you save, change or delete files fragmentation happens to hard disk into different locations and your computer slows down/heat up as it has to look in many different places to open a file. Disk Defragmenter is a tool that rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently.
This program is already available in every computers but it takes time to defragment like 2hrs-10hrs (works like turtles speed) which is time consuming. Well I have found completely new software which will take 2minutes-5min only(works like horse speed) and the software is speeditup. "Speeditup" is available free and you can easily download.
