How Ruby handles folders?

Ruby offers a special class for managing folders: Dir , the class provides the methods necessary for operations such as notification of the current directory: 

 



 # Know the current directory







 Dir.pwd
To create a new folder: 
 



 # Create a new folder







 Dir.mkdir ('nuova_cartella')
To move from the current folder to a new folder: 
 



 # Change the current folder







 Dir.chdir ('nuova_cartella')
You can read the contents of a folder through a simple loop: 
 



 # Read the contents of a folder







 Dir.foreach ('folder_name') {| file | puts file}
