How to run Disk Defragmenter in Windows XP
As harddrives read, write, and rewrite data, the files can become "scattered" or fragmented. Running Disk Defragmenter will help to reorganize the files, making them more compact, and often improving your computer's performance.
To start Disk Defragmenter in Windows XP:
1) Click on START>ALL PROGRAMS>ACCESSORIES>SYSTEM TOOLS, then click on DISK DEFRAGMENTER:
2) The Disk Defragmenter window will appear:
3) Click once on the drive you would like to defragment (usually the C: drive), then click on the "Defragment" button. The defragment process will begin:
4) As the drive is defragmented. the progress bar will advance to 100% (this may take an hour or more, depending on the size of your harddrive.) After defragmentation is complete, you can close the window.
Disk Defragmenter can significantly improve the performance of your PC, so it should be run at regular intervals. Depending on how heavily your computer is used, you should defrag your harddrive once per month, or whenever you notice your computer becoming slower.
