It would only be fragmenting the files that it writes to, not the ones
already on the disk.  Sure, a fragmented word processor document might
take a bit longer to open (though it'd have to be a large file for you
to notice), but the word processor is going to take just as long to
start up as it ever did.  Likewise with all the other unmodified files
on the drive (most of the OS and applications).  Writing a fragmented
file doesn't shuffle everything else around.

Things like large mail spool files have been about the only thing that
strike me as a fragmentation issue.  Most other files are rather small.

I was under the impression that the directory structure was recorded in
manner that's different from how the files are stored.
