You're right, that's what I meant.

an empty filename with an extension simply does not exist. That's by definition, and it doesn't matter whether or not someone likes it.

Ok.... you are missing the point
I already agreed that this is not a PB bug.
I agree that a filename can start with a dot.
I also agree that 'empty filename with an extension' can not exist.
The point is..... how do you detect the difference between 'an ERRONEUS empty file with an extention' OR 'a weired LEGAL filename with no extention'.

Anyway, I do a workaround, so no worry.
Case closed

I already agreed that this is not a PB bug.

I know. And I took the liberty of confirming it.

The point is..... how do you detect the difference between 'an ERRONEUS empty file with an extention' OR 'a weired LEGAL filename with no extention'.

You are right. I am missing your point, since you are artificially creating a problem that does not actually exist:

I have this software where customer enter a raw 'name' for there file and the extention is then automatically added.
I then check is a 'name' was entered and if it is valid with CheckFilename(name).
So i get things like "C:\user\benjamin\customerfiles\.lti"

First check the user input BEFORE automatically appending something to it. If it's empty, then it's an error.
