Hello there Wilko,
Sorry if I wasn't clear enough.
You don't need to change the logic already implemented inside the actions provided by the Plugin! You just need to use these actions in your flows.
Let's say you want to list the content into the Documents folder in an Android device. You just need to call the ListDirectory action in your flow and define the physical path as an input parameter.
This parameter DirectoryPath that I mentioned is one JavaScript output parameter that you should use as the Path input parameter in the ListDirectory action (or you can define it directly when you call the ListDirectory action without defining it via JavaScript).



However, as you can see in the link above, iOS devices and Android devices have different File System Layouts.
So, you should take that into consideration and define the physical path according to the respective platform:

Hope it helps.
Let me know if you managed to do it.
