Abstract: An apparatus and method for finding objectionable material contained within electronic files is presented. The apparatus consists of a computer system that is provided with a computer, a video display, a buffer memory, and at least one electronic file storage device capable of storing electronic files. Each of the electronic files is stored according to an operating system which incorporates a file name and a file name suffix. The method includes provisions for a real type property, a claimed type property, and a result type property for each electronic file. All of the electronic files are located on each of said storage devices for checking. During the checking process, for example, each file is checked to determine the file's real type property. If the checked file is determined to be a graphics file, then the file will be identified as a graphics file. If the file is not a graphics file, (i.e., it is a text file) then it is interrogated in order to determine if the text contains objectionable language.
