OK I will pick the images with PA and then backup the "files" folder (Android/data/com.maxmpz.audioplayer/files) On a new installation I could replace the files folder with the one I backed up. Is that correct? I can do that with X-plore file manager. Is there a recommended backup app that can do that?
If I go to settings/album art/delete cache will I lose all my images? What is the purpose of this function?
