Disk Defragmenter

Disk Defragmenter consolidates fragmented files and folders on your computer's hard drive so that each occupies a single, contiguous space on the volume. As a result, your computer can gain access to your files and folders and save new ones more efficiently. By consolidating your files and folders, Disk Defragmenter also consolidates the volume's free space, making it less likely that new files are fragmented.

To run Disk Defragmenter from the Start Menu, follow these steps:

Note: The following screens may vary slightly, depending on which options are selected.

  1. From the Windows Vista default Start menu, click All Programs, Accessories, System Tools, and then click Disk Defragmenter.

  2. In the User Account Control dialog box, click Continue.

  3. In the Disk Defragmenter window, select the appropriate option.
