so works a defragmentation program

defragmentation programs to speed up the hard disk you put back together scattered files. It comes to these scattered files to:

with loads of time, save and delete many files. Now the one saves man, for example, two files, 10 KByte large (o), the other 5KByte (x). Schematically, it looks like this:


deleting the first file again, the 10 KByte are free (-). Behind it are still the five other KB:


now you save a file that is 13 KB long (*). She of course not completely for space on the vacant 10 Kbytes. Therefore it occupies the vacated 10 Kbytes and additional space behind the other 5 KB:

* xxxxx *

these operations are repeated constantly in your system. With time, you will have many such split files. Now, the problem is that the disk head literally together must pluck some files when he loads the file.

because only a defragmentation program helps. The tool merges files that belong together. Thus, the reading head of the hard drive can read faster this data in one go. Our example would look like after the defragmentation:
