I don't know about k3b, but 'ls' will, by default, attempt to sort the
files before returning them. On large directories, 'ls -U' or 'ls -f'
are preferrable. There may be an option to k3b that similarly deals
with the files in directory order (worse yet, k3b may be attempting to
find the date order).

This is not to say that the basic fsfs design doesn't need changing for
that reason. In particular, I've found that NTFS behaves *very* badly
with over a few thousand files in a single directory (don't even think
about using a GUI)...
