Yes. It won't work - the API calls will reject it.

I just meant that it's not a problem on Win32 to have a file with multiple
dots in the name. There can certainly be *other* reasons for it. I don't
really see the need to have an extra dot in the filename in this particular
case, so I'd certainly be fine with restricting this one a lot more.
