If necessary, this process of division of directories may be 

continued with the addition of more levels. A file, in the context 

of a computer system, is a named collection of data stored on a 

storage device. Each file possesses some features and attributes, 

such as file name, file type or file access permission. To group 

similar types of files together, we create a directory and place 

those files in that directory. A directory may contain files as well as 

other subdirectories. This type of organized file structure is known 

as a multilevel or hierarchical directory structure.
