Make sure Look in is set to Web Folders

For the Folder name, use the entire URL of your domain

Open the files you wish to edit

If you have already created a web on your hard drive, you may wish to publish it to the new web on our server.  Again, use the entire URL for the site to be published to.  We have found that once a site is published to the web server, it is best to do any further editing by opening the files from the web server rather than re-publishing the web. 

Hint: to add files to an existing web on the server, you can click on File and choose Import, then choose the files on your hard drive that will be imported (transferred) to the web on the web server.
