You can make synchronize non-recursive by using -filemask=|*/.

Or use put with -neweronly:

Hello.

I try to find simplest way to put (and overwrite) only newer files. Only one file at time.

* https://winscp.net/eng/docs/scriptcommand_synchronize is not an option, because synchronize automatically create all subdirectories.
* option confirm off – results unconditional overwriting
* I am very lazy to read output of remote stat to compare with local times.

Any ideas?

Thanks all in advance,
Sincerely, Stas Fomin
