Hi @Squashedman. Here are the results of my searches. I'm sorry I wasn't able to find anything. But I hope the results help you and other newbies.
Search string: folder timestamp
252 matches
I scanned all the post headings. I only opened a post if the heading looked promising. No posts referred to folder timestamps, only file timestamps.
No post referred to creating a new folder in the target.

For info, to help other people, I think a better search string might have been "create new folder timestamp", because I thought it would be more "restrictive", but still valid. But that still produces 252 results

Search string: create new folder timestamp
Ignored: create new folder
So that explains the identical results. The first query was ignoring "folder", and the second query was ignoring "create new folder". Interesting concept

I then tried a google search using this forum link:
site:
www.dostips.com folder timestamp robocopy OR xcopy
That produced "about 46" results. Based on the titles, plus the 3-line preview, none of these helped. (I suppose some people on this forum might say that I should read every line of every search result - but I don't really have the time for that - sorry.)
I tried StackOverflow. I'll include the links I searched, because these might help dozens of other forum users duplicating each other's searches.
The following list has each search term followed by a link resulting from that term.

Stack Overflow is a great forum. The guys are super-helpful, and you can see that each post gets dozens of replies plus comments. The only problem for newbies such as you and me is that every answer is different, and in many cases the OP does not say which answer solved her problem. The other problem of course, is that they speak to each other in hexadecimal rather than English
There are still a lot of other forums to search. I'll report back with the answers in order to help other people on this forum.
Thanks.
