How to access the full file system in Android 7 and higher? I am running Android Nougat x86.But in Android Nougat, one of the adverse changes is the inability to even view the files. They are invisible, apparently even to root app.

I already tried root explorer in the VM. But that failed. /storage/emulated appears as empty, despite there is a directory called /storage/emulated/0.

How do I show all files to the file managers?

Update: The terminal emulator in superuser mode actually shows these hidden files.
Use a different file manager, e.g Solid Explorer, Es File Explorer, Asus File Manager or Root Explorer.
