OK for those interested, I just completes a 240 60-sec exposure Autorun session.
When completed, the "Log" directory did not show up in ASIAIR+, but when I removes the USB and put it in my computer the directory and *.txt files were all there.
Not quite sure why you would set it up that way - but there must be a reason.
Anyway, now I have 240 exposures to put together (and a log file to observe) !!
