WebDAV

Web-based Distributed Authoring and Versioning (WebDAV) allows you to set up a folder for a remote Web server (e.g. your WebCT server) on your local computer. You'll find it easier and quicker to manage your course files by using WebDAV because you can drag and drop folders and files into and out of the "My_Files" folder of your WebCT course(s). The main advantage of using WebDAV is the fact that you can upload and download multiple files instead of one file at a time.
