Plugin reads all files in folder and subfoldres and displays it on the website as clickable tree. Plugin register path to folder within wordpress upload folder, therefore add only relative path to the folder you want to list. When the path to folder is properly set, just copy the shortcode and past it anywhere to the page where you want to show the listing. Please keep in mind that this plugin is not suitable for listing thousands of items since it loads all the information at once. There are two layout available: horizontal (vertical on mobile) and vertical. You can define path and layout within the shortcode to use the plugin in serveral places and list different folders: [simple-ftp-directory-lister layout=”horizontal” path=”/path-to-folder”]. More information in settings of the plugin.
