getting to know on which files an app is working

[tsolignani]

Good evening, folks.

I use an app for audiobooks, listen audiobook player.

I would like to know in which directory it's working, for I would like to record notes into the same directory as text files while listening to the current book.

I tried file observer as a trigger to get the current working path, with no joy for either it doesn't work or it gives too much results (when accessing the whole library).

So I wonder if there would be a way to get to know the current working directory or file/s the app is working.

Maybe with general broadcast? How do I know what an app is broadcasting, though?

Or like what?

Any hint would be appreciated.

Thank you very much.
