Question: I'm new to PhpStorm and wondered if it's possible to show the full file path for an open file without hovering the mouse over the file tab?

I can only find this; <http://www.jetbrains.com/phpstorm/webhelp/navigating-to-file-path.html>

In Eclipse based IDEs the current open file path appears in the title bar.

Answer: 
Unfortunatly the only option you have is for it to show the path for non-unique filenames.

You can also see the path and navigate the files using the Project tab (ALT + 1).
