WebDAV allows you to easily transfer files and folders from your local computer to your Resources or Drop Box folder in My Workspace or in a site. WebDAV stands for "Web-based Distributed Authoring and Versioning". It is a set of extensions to the HTTP protocol that allows users to collaboratively edit and manage files on remote web servers.
Once you have set up WebDAV, your computer will treat your Resources section like any other folder on your local system. You will be able to drag and drop files and folders from Resources just as you would in My Computer or Computer in Windows, or the Finder on a Mac.
For more information about WebDAV, including technical specifications and major features, see the WebDAV FAQ.
Setup options: For Windows, you can download AnyClient for WebDAV connections, or set up a connection using the native Windows WebDAV support. Mac OS X 10.4 (Tiger) and newer supports secure WebDAV connections in the Finder. You can also use Cyberduck or AnyClient. Depending on your specific operating system version, you may find one method performs better than another.
