KB19516, and the other KBs linked at the bottom of it, are
interesting and relevant, and may provide a level of detail
which coordinates with what MCL and CO have informatively
contributed to this discussion.

(Since apparently not mentioned before, I'll just note that
"fragmentation" is related to the designed arrangement of how
file blocks are laid out on the surfaces of the disk platters.
Ie, a file's blocks may well not be strictly contiguous due to
eg the relation of read or write timing to disk rotation speed.
So fragmentation may be said to be when the way a file's blocks
are recorded on the disk is not the optimum.)
