A communication apparatus determines whether a file selected by a file selection unit is of a format analyzable by the communication apparatus. If it is determined that the file selected by the file selection unit is not of the format analyzable by the communication apparatus, the communication apparatus restricts selection of a predetermined protocol included in a plurality of protocols. The communication apparatus further determines whether the protocol selected by a protocol selection unit is a predetermined protocol. If it is determined that the protocol selected by the protocol selection unit is the predetermined protocol, the communication apparatus restricts selection of a file of a format not analyzable by the communication apparatus.
