Where is Android Emulator Internal Storage

If you want to view the folder/file structure of the running emulator, you can do that with the Android Device Monitor which is included with the SDK.

Specifically, it has a File Explorer, which allows you to browse the folder structure on the device. It also has buttons which give you the adb push/pull functionality but from a GUI if this is easier for you to use.

In Android Studio on Mac you can go to View -> Tool Windows -> Device File Explorer. Here you can use a finder-like structure.
