XPATH <message-id>

    The XPATH command is used to determine the filenames in
    which an article is filed. It first appeared in INN.

    The required parameter message-id is the message id of an
    article as shown in that article's message-id header. According to
    RFC 1036[3], all message ids for all articles within the
    netnews environment are unique, but articles may be
    crossposted to multiple groups. The response to an XPATH
    command will include a listing of all filenames in which
    an article is stored separated by spaces or a response
    indicating that no article with the specified message-id
    exists. The returned data is only useful if the news client
    knows the implementation details of the server. Because of
    this, it is recommended that client avoid using this command.
