prompt: Your task is to convert the following English description into an ASCII tree format.
  
  internal is a origin directory that collects 3 subdirectories: command, options and ui.
  At the main level, 'command' encompasses 3 folders: adapter, ci, export.
  Within directory hierarchy 'command / adapter', Inside 'adapter', you'll find it appears to be unused.
  In nested path 'command → ci', The 'ci' folder remains unused.
  At level 2, in directory path 'command → export', 'export' stores 1 folders: testdata.
  At level 3, in directory path 'command / export / testdata', 'testdata' houses 1 folders for testing purposes.
  Within directory hierarchy 'command / export / testdata / snapshots', The 'snapshots' compartment contains nothing at present.
  At the main level, 'options' has yet to be populated.
  At the main level, 'ui' contains 1 directories: v1.
  At level 2, in directory path 'ui → v1', 'v1' carries 6 some directories.
  At level 3, in directory path 'ui → v1 → app', The 'app' container stands empty.
  Within directory hierarchy 'ui > v1 > format', Inside 'format', you'll find it holds no subdirectories at the moment.
  Within directory hierarchy 'ui / v1 / key', The 'key' collection remains unused.
  In nested path 'ui / v1 / layout', 'layout' comprises 1 child directories: compound.
  At level 4, in directory path 'ui / v1 / layout / compound', The 'compound' directory is currently empty.
  Within directory hierarchy 'ui > v1 > view', 'view' is devoid of content.
  In nested path 'ui > v1 > viewmodel', 'viewmodel' maintains 1 subdirectories: testdata.
  At level 4, in directory path 'ui → v1 → viewmodel → testdata', The 'testdata' collection contains nothing at present.
