As a file system is used, data tends to become more and more
scattered across the disk, degrading performance. A disk
defragmenter simply re-organises the data on the disk, so that
individual files occupy a single sequential set of disk blocks,
and all the free space on the disk is collected together in a
single region. This generally means that reading a whole file
is faster, and disk accesses in general are more efficient. |
