The present invention aims at providing a cellular telephone apparatus capable of enhancing usefulness of file-sharing, as well as a file sharing method for use with the cellular telephone apparatus. When a file sharing request is issued, a communications control section 14 prepares a short message including a cellular telephone apparatus's own IP address, and transmits the short message by use of a short message service. Further, upon receipt of a file sharing request sent by means of the short message service, a telephone number of a sender is extracted. Further, a telephone directory application 20 is launched, to thus determine whether or not the extracted telephone number coincides with the telephone number registered in a telephone directory database 22. If the telephone number is stored, a display section 26 displays an inquiry as to whether or not file-sharing is allowed, while taking a name stored in the telephone directory database 22 associated with the extracted telephone number as a sender of the file sharing request.
