Synchronizing folders by timestamp issue

Hello, Administrator.

I currently have the following requirement:
I need to synchronize a local Windows directory to a remote FTP server, only syncing files and folders whose creation time is later than 2025-09-27.
I'm using a command similar to this:
In my local directory, there are both files and folders created before and after 2025-09-27.
When I run this command, I observe that:
Files and folders created after 2025-09-27 are synchronized correctly.
However, folders created before 2025-09-27 are also being synchronized—but only as empty directories (the old files themselves are not transferred).
This behavior deviates from my requirement. I only want to sync files and folders created after 2025-09-27, including their contents, and skip any folders that don’t contain qualifying items.

How should I adjust my command to achieve this?

Below is the structure of my local directory:

To avoid the empty directories, use ExcludeEmptyDirectories raw transfer settings:

Thank you, martin！ Using ExcludeEmptyDirectories is indeed a good idea. However, I've tested it, and found that it also filters out empty folders created after 2025-09-27, which is not what I want—I need to preserve empty folders created after 2025-09-27.
