Directories grow as they are filled the first time. If you use a shell
script with a wildcard to do the move, the shell will sort the list on
the command line as it expands it, so the names are linked into the new
directory in sorted order. However if you repeat this in the same
directory instead of creating new ones each time it may not continue to
work as existing empty slots may be reused in a different order.

Did you consider sharing a directory from the machine running distiller
and cifs-mounting it on the linux side to get ntfs behavior? Also, I'm
curious about the timing of the runs. It doesn't sound like the file
operations are grouped atomically. How do you ensure that the whole set
is present when distiller starts, or that only one set is present? If I
were doing it, I'd probably create a new tmp directory for each set of
files (which should fix the ordering as a side effect) and rename it to
the expected name after all files are present so you see all of them or
none. Or, I might put cygwin sshd on the windows box and use scp or
rsync to copy the files over in a batch, then start the Distiller run
(if you can start it from the command line).
