The other way around, right? What you describe here as 1.6's behaviour is in fact 1.7's behaviour (and vice-versa)... > Is there any rational explanation, any underlying > reasoning, principles, ... ? > When a directory is removed, then everything under it (all children and descendants) implicitly ceases to exist too. (Consider the grandfather paradox.) So I can see the 'D subdir/a.txt' notification as redundant. On the other hand, after the move two new nodes exist: 'subdir2/' and 'subdir2/a.txt'. So it would be appropriate to generate notifications that allow the client to infer that both of them exist. There are several options to do that: perhaps 'A + subdir2/' or (more accurately) 'A subdir2/ has_children=True', or 'A subdir2/; A subdir2/a.txt'. > Cheers, > -- > Johan
