I have an app that allows you to build a library of audio and video files. I liked it so much that I downloaded many GB of mp3 audio files and now have a full internal storage.
My phone does not allow the option to move any apps to SD card, unfortunately and it has a locked bootloader so it cannot be rooted
I contacted the developer of the app and they told me that the files are in a hidden directory.
So be it. But, there is about 28 GB of mp3 files hidden somewhere. Can you help me find them so that I can move them to the SD card ? I can plug into a Linux computer or a Windows computer.
