What is the effect of the "ATTRIB" command in DOS?

• A. To change the attributes of a file
• B. To delete a directory
• C. To copy a file
• D. To display directory contents

Answer: (A)

The "ATTRIB" command in DOS is specifically designed to change the attributes of a file or a directory. Attributes are metadata associated with files that dictate certain behaviors and permissions, such as whether a file is read-only, hidden, system-protected, or an archive file. By using the "ATTRIB" command, users can add or remove these attributes, which can affect how the operating system interacts with the file and how it is displayed in file listings. For instance, if a file is marked as hidden, it won't show up during a standard directory listing unless the command specifically allows for hidden files to be shown. Conversely, using "ATTRIB" to set a file as read-only prevents it from being modified or deleted unless the attribute is changed again. This command is essential for managing file properties effectively within the DOS environment.
