2. Fragmentation happens to a volume over time
as you save, change, or delete files. The
changes that you save to a file are often
stored in a different place on the volume than
the original file.
Fragmentation makes your hard disk do extra
work that can slow down your computer.
Removable storage devices such as USB flash
drives can also become fragmented.
3. Disk Defragmenter rearranges
fragmented data so your disks
and drives can work more
efficiently. Disk Defragmenter
runs on a schedule, but you can
also analyze and defragment your
disks and drives manually.
