Defragmenters are software or utilities used to reduce the amount of the fragmentation on the computer, making the contents of the disk to store the pieces of each file close together and contiguously. Hence, it will become easier to access the files that we want to read or write. This will not be a problem for a brand-new computer, but as time goes by, disk fragmentation will be the main factor which slows down the computer for the more fragmented the computer is, the slower it will be when trying to access some files.
