Run Disk Defragmenter on your PC hard drive periodically (monthly). Disk fragmentation occurs when files are deleted, software is installed or removed, internet browser cached information, etc., which leaves the data scatter over the disk rather then being continuous. This slows down retrieval of web pages, files and programs. Running a defragmenter realigns data consecutively on the disk and improves performance. 

Defragmenter Procedure. Depending on the size of the disk drive, file activity and frequency of defragging, the process may take an hour. We recommend you do not use the computer while the disk is being reorganized and that you start the process then go to lunch.

• Close all applications
• Deactivate the antivirus software. For Symantec (Was Norton�s), right click on the shield in the system tray and click on �Enable File System Realtime Protection�. The check mark will be removed.
• Run disk defragmenter by going to Start/All Programs/Accessories/System Tools/Disk Defragmenter

When the process is completed, reactivate Symantec by right clicking on the shield and click on �Enable File System Realtime Protection� - the check mark indicates it is active.

Note: The disk defragmenter can be cancelled by hitting the Stop button with no problems. However, wait until the program has fully stopped before closing the application.
