Using Disk Defragmenter

Defragmentation
The process of rewriting parts of a file to contiguous sectors on a hard disk to increase the speed of access and retrieval. When files are updated, the computer tends to save these updates on the largest continuous space on the hard disk, which is often on a different sector than the other parts of the file. When files are thus fragmented, the computer must search the hard disk each time the file is opened to find all of the file's parts, which slows down response time.

Using Disk Defragmenter

You might need to be logged on as an administrator or a member of the Administrators group in order to perform some tasks.

Disk Defragmenter consolidates fragmented files and folders on your computer's hard disk, so that each occupies a single, contiguous space on the volume. As a result, your system 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 will be fragmented.

To open Disk Defragmenter, click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter
