Please can you explain in more detail what it is you are doing and what it is you want.
For example if you have several files open in the editor view you can tell the file name associated to the active segments by looking for the document markers as noted in orange or by using the navigation 
tree as seen on the far left on my screen print. 



We also have solutions where users can stamp entries from the TM with the file name.
App link here

So once I know more about what it is you are trying to achieve, I can perhaps give you further guidance
