Defragmentation

Defragmentation is the process of locating the noncontiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file. Defragmentation reduces data access time and allows storage to be used more efficiently.

Advantages of Defragmentation 

1. Faster ApplicationsPrograms run faster and more efficiently when the data is grouped together for easier access.
   
2. Extended HardDrive Life The mechanical parts of the drive have to travel less distance when the data is all in one place, thereby reducing wear and tear on the drive itself.
   
3. More Efficient SecurityWhen an anti-virus program scans your hard drive, it takes less time when your drive is less fragmented.
   
4. Reduced ErrorsThe process of defragmentation can often point out and avoid bad sectors that could potentially cause damage if your data was saved in this area.
