Thanks for your speedy reply!
I think definitely not GUI: I want a one-liner command line statement to slip into a
as part of my Microsoft Access automated CSV export and ship to remove mysql server. Having tried a bunch of other things, this was the method I landed on, and ftp.exe which ships with Windows doesn't support TLS.
The "/*.*" refers to a GUI dialog prompt for destination filename that pops up just before the ftp PUT operation when I run the one-line cli command shown earlier:

When I hit Enter (accept the default "/*.*"), the transfer goes through without issue and the specified/desired single file is placed, named as it was on my source client machine running the WinSCP file transfer command. I suspect there is another option to either "don't prompt me" or "destination file should be named XYZ", but I haven't seen it.
