DAV Explorer
The user interface for the DAV Explorer is similar in look and functionality to the Explorer program which is provided by the Windows operating system. The DAV Explorer is a useful tool for interoperability testing a WebDAV server, since it is capable of exercising the majority of the functionality specified in RFC 2518, the WebDAV Distributed Authoring Protocol specification, while logging the protocol stream. However, DAV Explorer can also be used for remote namespace management, and has collaboration support for groups which employ a lock-download-work-upload-unlock authoring process.
