Windows file systems are susceptible to fragmentation, regardless of the type of file system or the type of disk. When a volume contains many fragmented files and folders, it requires several additional disk drive reads and more movement of the disk drive heads to collect the various pieces, resulting in Windows taking much longer to read a file. Similarly, creating new files and folders also takes longer when the free space available on the volume is scattered. If the free space is not consolidated, then subsequent files written to the volume will more likely be fragmented.

Disk Defragmenter is both a Microsoft Management Console (MMC) snap-in and a command-line utility that can be used to optimize NTFS- or FAT-formatted volumes. Disk Defragmenter rearranges files so that files and free space are consolidated. A reduction in fragmentation results in a reduction in the amount of mechanical movement required to locate all clusters of a file.
and the method of disk defragmentation is Disk Defragmenter MMC is based on the full retail version of Executive Software Diskeeper. The version that is included with Windows XP and later provides limited functionality in maintaining disk performance by defragmenting volumes that use the FAT, FAT32, or NTFS file system.

The first two methods take you to a standalone window containing Disk Defragmenter. The last method opens Microsoft Management Console and displays Disk Defragmenter as one of the snap-in modules.

When Disk Defragmenter first opens (Fig. 01) you'll see a list of the hard drives displayed at the top of the screen. The Estimated Disk Usage Before Defragmentation and Estimated Disk Usage After Defragmentation will be blank until a drive is selected and the Analyze button is clicked. In the screen shot above, I've already analyzed the drives as evidenced by the Session Status showing as Analyzed and the Estimated Disk Usage Before Defragmentation area containing a graphical representation of the drive fragmentation.

After the Analyze button has been clicked and the process completes the window shown above (Fig. 02) opens with a brief recommendation of what action Disk Defragmenter thinks should be taken regarding the drive. It's important to note that this is just a recommendation based on the percentage of fragmented files to total files and doesn't prevent the drive from being defragmented if you feel it needs to be done and might improve system performance. If you want to go ahead and defragment without more information, click the Defragment button. If you're in agreement with their recommendation and don't want to defragment, click the Close button.

well Aryan, As advanced as hard drives have become, one item they are not very good at is housekeeping, or maybe that should be drive keeping. When files are created, deleted, or modified it's almost a certainty they will become fragmented. Fragmented simply means the file is not stored in one place in its entirety, or what computer folks like to call a contiguous location. Different parts of the file are scattered across the hard disk in noncontiguous pieces. The more fragmented files there are on a drive, the more performance and reliability suffer as the drive heads have to search for all the pieces in different locations. The Disk Defragmenter Utility is designed to reorganize noncontiguous files into contiguous files and optimize their placement on the hard drive for increased reliability and performance.
Accessing Disk Defragmenter

Disk Defragmenter can be opened a number of different ways. The most common methods are listed below.

* Start | All Programs | Accessories | System Tools | Disk Defragmenter
* Start | Run | and type dfrg.msc in the Open line. Click OK
* Start | Administrative Tools | Computer Management. Expand Storage and select Disk Defragmenter
