that) is that the way linux file systems work make them not fragment. 
Instead of writting everything at the very first place if finds, they
try to keep things together.  Windows file system, on the other hand,
places everything in the first place it finds.  This makes a file that
should be contiguous on disk, be fragmented in different places.

Maybe I'm talking nonsense here but I have been using linux for quite
a few years now and I had never defragmented my disks.
