On my currently working Android 4.4 phone, much of my apps and data is on a MicroSDHC card and I am trying to find what to preserve and port to a new phone. As I am trying to move from an old phone to a new one and had not anticipating significant changes in behavior, I am rather confused on how to proceed and am entirely unprepared.
When reading the MicroSDHC card outside of the phone via a dedicated card reader there is a folder called .android_secure with 18 files all with .asec extension. What are those files? And can they be used somehow to help migrate to a new Android 7.0 phone?
Note that when mounting the phone, all the folders in the MicroSDHC card appear except for that one, so you have to read the card externally to see it.
This is about the concept of the folder which you can only figure out that it is for applications if you know already the answer.
