I download audiobooks from my local library's Cloud Library page and they are stored on my Samsung S9 phone. I listen to them with the Cloud Library android application. When I download the audiobooks they are generally described as being mp3 files on the source servers.

My phone has a file system and I can see at least some of that with the My Files app. But I can't seem to find any mp3 files anywhere or any folder that seen to be associated with the Cloud Library app.

Is part of my phone's android file system hidden from me? If so, is there a way to view the hidden portion?

If the audiobook mp3 files are saved into files of a different format what are the file names used? And where would they be located?

Any links or other help with the android Cloud Library is appreciated.
