I am using German version 4.1.5 build 410 with the Norton Commander style interface.
A local file with the extension .bin is not visible.
I have checked the general settings: "show hidden files" (translated from the German interface) is selected, although it does not have the attribute hidden nor any other.
Is there something I missed or is it a bug?
Can you provide me your email address, so I can send you a debug version of WinSCP to track the problem? If you do not want to post the address here, you can send me an email. You will find it (if you log in) in my forum profile
