I warn you that since Android 11 you cannot see the contents of the DirDefaultExternal folder from smartphones.
It marks you that the Android / Data folder is empty.
Google removed the ability to access these folders without using a computer. It's called "scoped storage".
Hello.
Maybe I explained myself wrong.
When you look at the contents of that folder from the file manager you have on your Android 11 smartphone, it tells you that the Android / Data folder is empty.
On the other hand, when you connect your smartphone to your computer using a USB cable, you see the content of that folder, that is, the different DirdefaultExternal folders of each application.
