What does the DOS command 'Dir /ad' display?

All files
Hidden files
Directories only
System files

The correct answer is: Directories only

The command 'Dir /ad' is used in the DOS command line interface to display a list of directories only. The '/ad' switch specifically instructs the command to filter the results and show only those entries that are directories, excluding files. This command is useful for users who want to quickly view the structure of folders within a directory without having to sift through individual files. By isolating directories, this command helps maintain a clear focus on folder organization, making it easier for users to navigate their file systems.
