Hi! As a preface, I have zero experience with html. When I try to edit the file in TextEdit on Mac, it offers to convert the file: "Documents with graphics and attachments will be saved using RTFD (RTF with graphics) format. RTFD documents are not compatible with some applications. Convert anyway?", and I can only convert, duplicate, or cancel, which means I'm working with an RTFD file either way. The problem is, I cannot save or export the file as HTML once done. So I'm left with an RTFD file... I'm not sure what to do from here. Would be really thankful for any tips.
