property Group: string;
The Group property holds the name of the group to which the file belongs.
The string should be of the form "[email protected]_domain". This will allow a client and server that do not use the same local representation to translate to common syntax that can be interpreted by both. In the case when no translation is possible for the client or server, the attribute value must be constructed without "@".
Note: This property is supported starting with version 4 of the SFTP protocol.
