Copy Web Site is a tool used to deploy the Web site by copying its content files. The Copy Web Site tool also checks whether or not the latest version of a file is present at the destination. If files of the most recent version are found at the destination, then the Copy Web Site tool does not superimpose the older version of files. The Copy Web Site deployment tool consists of the following main entities:

* Project source - Specifies the source directory, which contains the contents and references of a Web site at development time. In simple words, you can say that the project source specifies the site that you currently have opened in Visual Studio 2010. The Copy Web Site tool picks all the files for deployment from this location.
* Project destination - Specifies the destination folder where you have to deploy the application. This destination directory can be placed on remote computers or servers, which allow you to copy the Web site contents using the Front Page Server Extensions, FTP, or HTTP protocol implementations for content transfer.
* Synchronizing two Web sites - Synchronizes two Web sites by copying each other's files. Synchronization checks the files on the local and remote sites and ensures that all files on both sites are up to date.
