A friend runs a website, has loads of space and agreed to let me use some of it for my site. When I log in to publish my site I can see all his site files plus a folder with my files in, which he loaded from a disc. To update the site should I simply double click my folder and tell FP to publish local to remote, replacing just the changed pages ? I tried to upload a test changed file and it went into the main site.
That would depend on whether a sub-domain can be created, of course, and whether it's worth doing in this case. You may be happy with the current setup if those who need to view your site can be provided with the correct URL, ie. click here friend's site.com/html/your site's index page.html
