My file has gotten pretty large and I wanted to make a new prototype that represents a different journey through the app. Since there are a ton of drivers and components already hooked up, ideally I could remove the unused components and artboards while keeping the working bits that I need. However, when I delete them – the components remain and the file size is not reduced despite being a much simpler prototype. I am unable to copy and paste the artboards I need to a new file. And even grouping the contents within the artboard and attempting to copy those over does not seem to work.
