PhilRodford said the listing is "recursive". Which means it will list the contents of every subdirectory. And the contents of every subdirectory of every subdirectory. And so on. Until everything has been listed. If you think you have to manually go into every subdirectory, then you don't understand what "recursive" means.
PhilRodford also gave you specific commands to try. He also said "check that that is what you want".
Did you try what he gave you? If so, did it produce what you want?
If you didn't try it, then you should do so, so you can see what it does. If you try it and it doesn't do what you want, then by all means, post again with a specific description of why it's not what you want. But if you haven't tried it, and you don't know what "recursive" means, then complaining is premature.
