Expected behavior check

I wrote several Windows batch scripts several years ago and I included the line below. I needed to copy all files from a local folder to a remote folder and exclude the sub directory that resided in the local folder. I think that is why I included the below line. It's been awhile since I've done anything in WinSCP so I hoped others could confirm this is the best way to accomplish what I intended to do or if I should change it because the current way I wrote could cause unintentional issues? It's been working all these years but feels kind of hackish but perhaps it's fine as is?
Where macrolocal is the local directory with a subdirectory inside it. Macroremotein is as you might suspect the remote directory.

Canonical way to exclude subfolders is: -filemask=|*/.
See How do I transfer (or synchronize) directory non-recursively?
Additionally, you have a stray double quote at the end of the command.

So the command should be:

Curious how the slashes matter in this context? In my example I used
But yours is
Using -filemask does the convention not have to follow the target system? Obviously it doesn't but I'm curious about that. Forgive my ignorance :)

Slashes do not matter in partial file masks.

Hi,
I’ve used -filemask before, but I’m curious—does the order of the patterns in the mask affect performance or the way files are processed during a transfer? For example, if we exclude multiple subdirectories with |*/dir1/|*/dir2/, is it handled sequentially or all at once?

Thank you.

Sorry, I do not understand what is "sequentially or all at once".

Hi, using -filemask=|*/ as Martin suggested seems like the best way to skip subfolders. About the order of the mask, I think it doesn’t change much since all patterns are checked together.
