Maintenance 3
Running the Disk Defragmenter Program
When Microsoft
®
Windows Vista™ stores files on your hard disk drive, it often divides
them into multiple pieces (or fragments) so they fit into available space on the drive. When
you attempt to open a fragmented file, it must be retrieved from more than one place, so
the process takes more time.
The Disk Defragmenter program groups the fragmented files together on your hard disk
drive to improve computer performance. This does not affect the location of files and
folders on your computer.
1 Save your work and close all open programs.
2 Press the Ctrl key, the Alt key, and the Delete key at the same time.
3 Click Start Task Manager.
4 On the Applications tab, select all the programs that are listed, and then click End
Task. Close the Task Manager.
5 Click the Windows Start Button, choose All Programs, Accessories, System
Tools, and then click Disk Defragmenter.
6 Click Defragment Now.
If Disk Defragmenter repeatedly starts, a hidden background program is still accessing the
hard disk drive. Restart the computer in Safe Mode and run the Disk Defragmenter
program again:
1 Click the Windows Start Button, click the arrow next to the
Lock button, and then click Restart.
2 Press the F8 key as soon as the first logo screen appears.
3 On the Windows Advanced Options menu, use the arrow keys to select Safe Mode
and press the Enter key.
4 Press the Enter key again to select the operating system.
5 Log on to Windows Vista. When the Desktop message appears, click Yes to continue
in Safe Mode.
6 After Windows Vista starts, use the previous procedure to run the Disk Defragmenter
program.
NOTE: The Disk Defragmenter program may take a long time to complete. You can run it
unattended overnight.
