OBB file is APK Expansion Files. These files carry encrypted data including media and graphics that is not included in the APK file. Developer will add one or two expansion files to the APK, each file can be up to 2GB. Conceptually, each expansion file plays a different role:
The main expansion file is the primary expansion file for additional resources required by your application.
The patch expansion file is optional and intended for small updates to the main expansion file.
The specific location for your expansion files is:
<shared-storage> is the path to the shared storage space.
<package-name> is your application's Java-style package name.
For each application, there are never more than two expansion files in this directory. One is the main expansion file and the other is the patch expansion file (if necessary). Previous versions are overwritten when you update your application with new expansion files.
