Use Content Provider to view a file which is in app A internal /data/data/com.example.com/files/a.txt be readable to in all apps

Question

I have an app A which has a file in /data/data/com.example.com/files/a.txt, Now I want that using content provider my app B can call that file from A internal directory I have seen implementations of SQLDB for a content provider where making provider exported and using contrast and content resolver its possible but I have not seen any such with a file is that possible. Here in this training google has shown for SQLDB is that same possible for files
