Defragment your computer disks
2011-01-14

As you save, edit and erase files from your computer's disk drives, files in those disks gets fragmented. There is a software called defragmenter within all versions of Windows. You should run it once in a while (like once every 3 month) to help speed up your computer.
It is a good idea to replace (upgrade) your hard disk drive if you are using it for more than 3 years. When you copy all your files from the old hard disk to a new one, you will not have any fragmentation. Then you can format the old disk and use it as a backup.
