Schedule a weekly defragmentation

If it seems like your computer has gotten slower since you bought it, it probably has. One of the biggest factors that slows down your computer’s performance is fragmentation, a situation that occurs over time, in which files on your hard drive become divided into small pieces. Your computer must read a file to open, save, or close it. So when it reads each piece of a fragmented file separately, the effect is that the file can seem “slow” when you’re working with it.

Defragmenting your hard drive is the process of putting all the scattered pieces of files back together. Microsoft Windows XP includes a tool that will defragment your hard drive for you. To keep your system performing well, it’s a good idea to have Windows XP automatically defragment your hard drive every week.

Windows XP will defragment your hard drive at the time you have scheduled. During defragmentation, a black window will open. If you happen to be working at your computer when the window opens, you can ignore it. The window will automatically disappear when defragmentation is complete. You can use other programs during defragmentation, but you may prefer to schedule defragmentation at a time when you won’t be using your computer.

Defragmentation works best when you have plenty of free space on your hard drive. For instructions on how to clear free space, read Maintenance tasks that improve performance.
