Which command should be used to display all files within the specified subordinate directory of the subdirectory? A. Dir \ pathname B. Dir \ pathname\pathname C. Dir / ch D. Dir \pathname\filename

The correct answer is A. Dir \ pathname.

The Dir command is used to list the files and folders in a directory. The pathname is the path to the directory that you want to list. To list all files within the specified subordinate directory of the subdirectory, you would use the following command:

Dir \ pathname

For example, if you wanted to list all files within the “Subdirectory” folder that is located in the “My Documents” folder, you would use the following command:

Dir \My Documents\Subdirectory

The other options are incorrect for the following reasons:

• Option B: Dir \ pathname\pathname would list all files within the “pathname” folder and the “pathname\pathname” folder.
• Option C: Dir / ch would list all files in the current directory that have been changed since the last time they were backed up.
• Option D: Dir \pathname\filename would list the file named “filename” that is located in the “pathname” folder.
