I formatted SD card as internal storage (Android 6.0) and it is confusing... I read that when the SD card is formatted as internal storage, it is also encrypted, so it can't be accessed trough windows for file transfer (if not rooted). OK, so I thought, there must be some practical way to transfer files such as books, movies, music, etc. from PC to SD card... I tried to make some folder (for instance, BOOKS) on my phone's internal memory, transfer the files in that BOOKS folder, then move that BOOKS folder to SD card. But, I can't find the location of the SD card, so there is nowhere to move that BOOKS folder. 1) What is the SD card folder location, if there exists one? 2) Is there some practical way to transfer files from PC to SD card? 3) What does "Migrate data" option actually migrates, APK's, pictures, videos,...? And how does it decide what is suitable for migration, on what criteria? 4) Is there a way to pick which files would be transferred to SD card?
