I have a website is about eight years old and is full of garbage. It has junked files and folders. It has HTML folders inside HTML folders. I have duplicate files which have to be removed. For example: I don't know what happened here but when my index page opens up in the browser and you click on a link on that page it goes to the same page again one level up. This is a duplicate file issue.
You can check this site out at:[my website]? here you will see when you click on Toronto painters on the top left hand corner the browser will point to the same page except one level up. When I was building this site I had hardcoded all the files to their actual web address as opposed to pointing to the file within the files directory in dreamweaver.
