http://wordpress.org/plugins/file-away/ to show the sub-folders and show its files and folders respectively, though I am not able to work out in the plugin itself. This plugin displays file download links from your server directories or page attachments in stylized lists or sort-able data tables
How I achieve it? I just worked in the plugin to show the directory and for the repetitive folder, I make another page and on another page, it shows up the list of the files and folders and shows it repetitively.
