This is complicated.

The answer depends on what you have chosen in CC's Settings / File names. To quote the FAQ on this subject

If none of the CC file name settings are chosen, CC's wireless device connection will use the file name provided by calibre, and CC's Cloud and Content Server connections will use the default CC template.

My guess is that you haven't checked any of the boxes. Because you are using the cloud connection, the default template is

{title} - {authors}

which does not use subdirectories. You can easily verify this by looking in the CC folder on your SD card.

I further guess is that you want to use something like the third template from the experiment described in the FAQ answer. That template creates a 3-level hierarchy. The first level is the first letter from the first author's name. I used that because all my authors are LN, FN. If your authors are FN LN then you might choose first_author_sort instead of first_author. The second level is the first author. As before, you might choose first_author_sort. The third is the title - author.

The goal of the exercise is to keep the number of file/directory entries in any given directory as small as possible. To that end, depending on the books in your library, you might choose to use the first letter of title_sort instead of the author for the first level. You would do this if the distribution of books-by-author isn't good (lots of clustering) but the distribution by title is better. You can get an idea of the clustering using the tag browser in calibre: group authors and title by first letter. You could also choose to use 2 letters in the first level, but that runs the risk of creating hundreds of directories at the top level, defeating the purpose of the exercise. Finally, you could choose to add a fourth level: perhaps the first letter of the title (or title_sort) or perhaps the two-letter author just below the top level containing the first letter of the author.
