I fumbled my way through learning EW well enough to produce a web site that actually functioned. The code was pretty sloppy, though, so I sent the site to a friend of a friend who offered to clean it up for me. He did a fine job with the cleanup, but he did the work in Dreamweaver.
I had purchased EW at retail and want to use that for future editing and upgrading of the site. What do I need to do to get his Dreamweaver work back into EW format? (i.e. the master.dwt and default.htm have been replaced with index.htm and style.css).
