What is

defragmentation Defragmentation is the process of optimizing and updating the logical structure of the disk partitions to organize files with a continuous sequence of clusters.Defragmentation allows faster reading and writing of files, resulting in increased speed of the various programs and the entire operating system.This happens because the read and write operations are performed at a higher rate than the random treatment.In a more simplified form defragmentation operation it is to reallocate the files on the disk so that they are located in contiguous areas.

large files take a few clusters.In carrying out recording on a blank disc belonging to the same cluster file written in a row.Crowded same disk does not have a whole area sufficient to accommodate the file.However, the record of the fil
e is still produced, if the disc has a few small areas of sufficient size to record total.The file in this case is written as several fragments.

file splitting into fragments during the recording process is called fragmentation.If you have a large number of fragmented files on the drive decreases the speed of reading the media, as the search for files containing clusters required time.When compared with other media such as flash memory, the search for them depends on how sectors are arranged so they fragmentation does not take place.

Some software needs to be sure the files were stored in consecutive sectors (for example, this requirement imposes a built-in emulator image files in the drive Zalman VE-200).From the need for defragmentation in this case will not save even installing the SSD.

How to defragment

Conduct defragmentation must be on file systems such as MS-DOS and Microsoft Windows, as they support the program does not protect the system components from fragmentation.It can start even at a nearly empty drive with a light load.

defragmentation is performed with the help of special programs, defragmenters that are among the applications pre-installed on the system and are able to literally collect files from their fragments.Their only drawback is the low-speed operation: expected completion of defragmentation is sometimes necessary for a few hours.
