Thanks for your report. How do you suggest to resolve the problem? I do not think there's a reliable way to parse the listing, if there a space in the a group or owner name.
Thank you for your answer.
I am not a programmer, so I will probably say something irrelevant, but Putty presents the names correctly. Can we "consult" its source to see how it's done there? Or does that case not apply at all to WinSCP?
This "problem" arises, for example, when looking at Samba directories whose files carry Windows permissions, which often contain spaces. The user ID numbers are of course not affected, this is a esthetic problem only. Nevertheless, it would be nice to fix it.
