The name of the open pdf file is not shown in the upper tabs.

Hello everyone, I usually work with several pdf files simultaneously, and I like to see the name of these open files ... 
But adobe reader only shows me "..." instead of the file name.
 I would like to know if any of you, you know if this can be modified so that the name of the pdf file appears instead of "...".
I enclose a capture of my problem.

Greetings community, and thanks in advance.
