What is a resource directory on a host?
A resource directory is a folder (or folders) on your host which hold some files.
Recommended backend environment for a website /web page is based on a structure.
A web page (or entire website) uses resources like images, scripts, css style sheets and other file types.
A good practice is to have all resources grouped in different directories like a directory for images, a directory (folder) to hold all the css style-sheet files, one for js scripts… so on.
But with an organized backend and management come some risks too and two of them are hacking and hotlinking.
Hacking, well.. everyone knows what hacking is, the general definition but hotlinking is defined much more simple.
Someone can access the root of your website by deleting a few characters from a URL.
Unprotected directory. Root path exposure.
You have an image uploaded on your host, open the full URL of the image in a new tab and delete from the very end all characters until the first / from end to beginning (right to left)
Now, if I delete the image name and extension I can access the images directory.
If it is not protected in any way, I can download or use any of the files available on this directory and here’s what I can define as hotlinking.
Create an index.html or index.php file and upload it to this directory.
File can be empty, can have a redirect or it can have some simple content with info and a link to main page. Read more on forum

How to create an index file?
Simply create a new file in Notepad or Notepad++ and save it as index.html . It can be empty or have some sort of content. An automatic redirect (thus I don’t recommend for big sites) or a text to inform visitor they are not allowed to visit that section of your website.
