This command was introduced in the LAN Manager 1.0 dialect. This command is deprecated. New client implementations SHOULD use the SMB_COM_TRANSACTION2 subcommand TRANS2_QUERY_FILE_INFORMATION.

This command MAY be sent by a client to obtain attribute information about an open file. The client MUST provide a valid FID in the SMB Request. The FID SHOULD have been acquired through a previously successful use of one of the SMB commands for opening a file. This command provides more information about the file than the SMB_COM_QUERY_INFORMATION command. The server response is limited to providing a 32-bit file size in bytes and is inappropriate for files exceeding that size.
