Thank you to Ross Moore for suggesting the use of the underscore.

I have had a second thought, and made some trials.

1) Apple Informations (cmd-I) : The answer is Name + extension is  
Fig.I.1.1; without extension, same answer. So MacOS is well aware  
that this name contains no extension.

2) Adobe Illustrator opens this file without any problem.

3) So does Microsoft Word, and you can read Fig.I.1.1

4) When you create a file named untitled.1.2.3, and open it with  
TeXShop, the application thinks it is a file named  untitled.1.2,  
with extension .3, and it suggests you to save it as untitled.1.2,  
with extension .tex. This means, only the segment delimitated by the  
last dot is considered as being the extension.

So, can I think that there is some flaw in the programming of  
\includegraphics, and that this flaw can be cured easiy ?
