Upload a Webpage

Hi everybody,
I’ve a question over here. I’m using Dreamweaver to create my website. After designed my webpage. I intend to use the free website such as Anglefire to upload my file. However, it fail. This is because Anglefire itself has it own index.htm file. It does not accept my index.htm that I’ve created in the Dreamweaver. Now, my problem is I can’t delete off the index.htm file that given by Anglefire. I’ll be appreaciate if anyone can assist me in this area. Thank you.
