A dialog box labeled Defragmenting Drive C: will appear (If a dialog box stating that your Drive does not need defragmenting, select the Defragment Anyway button). Next select the show details button (this will allow you a visual representation of the Defragmentation process). When Defragmentation is complete a dialog box will appear. Select close. Note: The time it takes to defragment is dependent on how fragmented your drive is and when the last time you ran the defragmenter utility. The more often you run it the quicker it will be).
