DEFRAGMENTING COMPUTER

Many of the PC users must have observed that as the hard-drive starts filling up, the computer starts slowing down. One of the main reason for this slowing down is Fragmentation of the File system. This problem can be easily corrected by Defragmentation. But before that let us have a look at what really is Fragmentation of file system.

Fragmentation
When the hard-drive is new the computer stores the files in continuous manner. But after some time gaps start forming between files (this gaps form due to deletion of old files or when the computer allocates excess space for the file.) As the hard-drive fills up the computer starts storing fragments of the files in this gaps. This greatly reduces system performance.


Defragmentation
The above problem can easily corrected by defragmentation. defragmentation reorganizes the files contiguously and closer to each other. This creates larger areas of free space which prevents from further fragmentation. Windows has a internal defragmenter but it is not highly efficient and it uses high amount of system resources thus affecting other system processes. Here are 2 of the best free defregmenters out there
