On WinSCP startup/connection panel, I clicked on:Tools > Preferences > Panels > Remote
And the checkbox mentioned above by tarrob does not exist (perhaps I'm using a newer version? 5.11.2).
However, I connected to the server and on the bottom of the remote panel itself I just noticed there's information about the number of hidden files.
I clicked on this text and the files showed up! :D
Hope it helps.
I'm on 5.13 now. Yes, this helped! Thanks.
