An automatic software configuring system includes a database storage section for storing therein a plurality of soft components. In the event that soft components are extracted from the database storage section and are combined together to thereby generate a file, a comment indicative of a storage location in the database storage section for storing a respective soft component extracted from the database storage section is added to the respective soft component. The automatic software configuring system further includes a device for identifying the respective soft component combined into the file and a storage location of the respective soft component by reading the comment; a device for identifying a comparison-target soft component stored in the database storage section; a device for identifying a soft component having a different content; and a device for replacing specified soft component in the database storage section with the soft component combined into the file.
