I’ve recently migrated a site and noticed that I can access all of my directories within my image folder. I’m aware that I can place a index.html in all of my file upload locations and have done so, but this is more for my clients. If they create a new file upload location they will not be aware of this potential security issue.
My question is this. On other sites that I have running ExpressionEngine I have no need to do this and accessing the file upload locations is not possible from the url, how is this done?
