The command used to display the list of files in a directory is "DIR." This command is fundamental in DOS and other command-line interfaces, allowing users to view the contents of a specified directory. By executing the DIR command, users can see the names of files, their sizes, and the date and time they were last modified.

Understanding the functionality of the DIR command is crucial for file management in a command-line environment, as it enables users to assess their directories, identify needed files, and navigate their file systems effectively. This command can also accept various parameters and switches to modify its output, such as sorting files or displaying them in a more detailed format.

Other commands listed, such as LIST, FILE, and SHOWFILES, do not serve this specific function in the DOS command environment. Hence, the reason DIR is the correct choice stems from its established role in displaying directory contents.
