Will I be able to use dreamweaver to make all the pages for my website and then do I upload them to file manager?
Does file manager accept dreamweaver files and will this way actually work? If not could you tell me how.

you can make your site however you want

then you upload your files via ftp or if dreamweaver has a built in ftp you use it

if you want to make your pages using the bravenet editors then use one of them
