   +--java
   |   `--org
   |       `--gradle
   |           `--sample
   `--webapp
  ```
  
  Convert this description:
  
  external is a fundamental directory that incorporates 2 subdirectories: app and node_modules.
  In the root directory, 'app' hasn't been filled with any content.
  In the root directory, 'node_modules' keeps 1 packages: external-esm-pkg-with-async-import.
  At level 2, in directory path 'node_modules > external-esm-pkg-with-async-import', Inside 'external-esm-pkg-with-async-import', you'll find it awaits content.
  Back to the top level.
