How to Run a Disk Defragmentation?


The storage of a file in several non-contiguous areas of a disk rather than a single contiguous until is called Disk Fragmentation. When a file is stored on a disk, the Operating System searches for the first available free block on the disk and stores the file there.

If the file you saved is too large according to the Operating System for one block then Operating System searches for the next block which have that much of free space. These blocks may not be in continuous form or may be scattered over the disk.

This fragmentation also slows down your computer system, or the retrieval of data. So, to remove this file fragmentation, a Disk Defragmenter program is used, that rearranges all files and directories into one contiguous area of disk and consolidates the free space in one contiguous block.
