(as per my reply to Andreas)

I've not mentioned it, but the entire logbook directory and subdirectories have to squeeze into a memory stick,
along with other data not at issue here.   Soon be too much for an 8GB stick, so that a factor of 100 down on
the available memory space.

But I can work with the solution I gave in the reply to Andreas.
