Thank you for your reply - it does help me when someone actually says something when something is wrong or questionable.

The DOS-PROMPT timestamps gives an elapsed time of

5:59:44.45
-
5:59:49.67
=
0:00:05.22 (HH:MM:SS.fraction of seconds)

So the duration is ~5 seconds (not 15 seconds - typo maybe?)

Do not know if this is nonsense, a fairly cheap "K-MART" Verbatim USB stick used which is not USB3 speed probably only USB2 or even USB1 speed).

Yes I agree that the EXACT same files/directories set is not used in all cases. To be screen capture compatible (not missing anything) - I am now standardizing on (9 files + 5 folders) for "everything" (as far as "simple and quick" testing schemes go). The 14 and 16 variation due to "local" identifier files with the idea that they would be visible in the last lines of the DIR shown in the screen capture.

Yes, I agree - I am gaining some experience in trying to design "testing situations" for LFN - well at least I am trying to contribute in the testing of doslfnMS.


Further "reports" by me will be more complex (messy) - I am aiming for EXTREME cases - just working with 9 files with 5 directories is a fairly trivial test set.


Many thanks for your input.
