you can fragment a PFS3 partition, if you fill it up. If there isn't
sufficient contiguous free space to save a new copy of a file, it will
be fragmented whatever filesystem you use.

That's what PFS-Defrag does. But first it runs Diskvalid to determine
which files are fragmented and need to be copied. It also preserves all
protection bits, which a normal copy operation doesn't.
