Disk Defragmenter Disk Defragmenter - this term is understood a special procedure that optimizes the logical structure of the hard disk partition to provide file storage in a continuous sequence.

fact that write files on the hard disk in a variety of operating systems, including Microsoft Windows, not always consistently performed .Saving files is performed on clusters - logical units of data storage.If the file is so "big" that does not fit on a single cluster, then recording on several clusters.

If the disk on which the file is recorded, is already filled by other files, free clusters, arranged in series, there may not be.In this case, the file is written in part in clusters located once like.This process is called file fragmentation .

this situation is typical of most file systems FAT - File Allosation Table - that because of the rather primitive algorithm, the degree of fragmentation is increasing.

What is disk defragmentation?

In principle, fragmentation of files was not would be no problem, if because of

it does not slow down the speed of the hard disk and the PC performance in general.

To read the requested file, the hard drive is positioning the read magnetic heads over the desired cluster.If the clusters in which the recorded files are "randomly", every time you need to re-position the read heads that significantly slow down the hard disk .

How to defragment the disk?

Disk Defragmenter runs special programs, defragmenter - they literally "collected" files bit by bit.But there is another, very good, a way to defragment the disk.He performed manually.The hard drive is enough to create a new logical disk (partition), and to copy the necessary files.This should first copy large files, and then - small.

disk defragmentation software can be divided into paid, free and built into the OS. For Microsoft Windows, starting with version NT 5 has a built-in defragmenter utility for the file system NTFS.

To defragment a disk in the Windows using this utility, you must go to the menu item "Tools" and select the item "Disk Defragmenter" (Start - & gt; All Programs - & gt; Standard - & gt; Tools - & gt;Disk Defragmenter).Having started the program, you must select a partition and click "analysis".After analysis, the program will show the degree of file fragmentation.

disk defragmentation software work very long - a few hours, in addition, for the duration of the defragmenter is not desirable to include any other programs.Therefore, as a rule, users perform a disk defragmentation at night when the computer is not loaded more than any other tasks.

Disk Defragmenter free performed using tools such as the Auslogics Disk Defrag, Power Defragmenter, Defraggler.Among paid programs to defragment your disk popular Diskeeper, O & amp; O Defrag Pro.

Virtually all programs, defragmenters allow you to work in manual mode, on their own time and defining the parameters vypoleniya Disk Defragmenter, and in automatic mode, when the program itself determines all the necessary parameters of its work.As a rule, at the end of the program for disk defragmentation give the user a detailed report .
