Adding files to source control
Expression Studio 3.0
The first step in managing a project is to add all project files to the source control repository. When you add new files to a project, you must add them to source control too.
In Windows Explorer, move the site folder to a location in the project workspace.
In Expression Web, click Site, and then click Open Site. Browse to the location to which you moved the site folder, and then click Open.
In the Folders panel, right-click the root folder of your site and click AddtoSource Control.
