Single click open files/directories policy?

Is there a setting to set single-click file/directory open in winscp?
I could not see it anywhere.
Thanks in advance,

Why do you expect there is one? Does any other software have such behaviour/option? If you want to navigate using a single-click, use the directory tree:
https://winscp.net/eng/docs/ui_file_panel#directory_tree

One good example of implementation of this very sophisticated functionality is 'Total Commander', a two-panel classic file manager where you can specify to 'Open files and directories with a single click' under 'Configuration>Operation>Main program' section.
Saying that, pretty much any file manager I've used would have this option or it would simply respect the system-wide click policy, apparently not WinSCP.

OK, I see. I didn't know that feature. Thanks for your suggestion. We will see, if more people ask for this.

Not a bother, much appreciate.
