   |   +--(.)feed
   |   `--(.)photos
   |       `--[id]
   +--feed
   `--photos
       `--[id]
  ```
  
  Convert this description:
  
  src is a origin directory that encompasses 2 subdirectories: main and test.
  In the root directory, 'main' groups 1 nested folders: java.
  In nested path 'main > java', 'java' appears to be unused.
  In the root directory, 'test' houses 1 folders for testing purposes.
  Within directory hierarchy 'test → java', Inside 'java', you'll find it remains unused.
  Back to the top level.
