Android Studio project folders not showing

I tried the all the approaches mentioned above but can't fix rather than fix it by a hardcore approach -

Step 1. Close your Android studio.

Step 2. Delete .gradle and .idea folder from your project directory.

Step 3. Open your project and you will see the files again.

Above your the file directory view in Android Studio is a drop down which currently is most likely set to Android. Change it to Project and you should be able to see all your files.
