| defragmentation
When you use the same file over and
over again, writing, rewriting, saving, and deleting parts of it on the
same disk, the file becomes fragmented. That means that although you can't
tell, your operating system is storing all the data from that file as
separate packages of information, distributed on different parts of the
disk. Although fragmentation does not lose the information contained in
the file, it does eventually slow down access to the file itself, because
the OS must search the whole disk to create the sum of the file's parts.
Defragmentation collects all those parts into one stream of data again,
speeding up your system. |
