1. In a computer platform which processes data files in an original specialized second format and which accesses a first format Container (CD.backslash.FILE) of data files and Directory organized as byte stream text files in a first format on a CD-ROM (31d), a method for re-creating original specialized second format files (MY/FILE/=) which duplicate the files and Directory information of said first format Container but is now organized in said second format, said method comprising the steps of: (a) unwrapping said first format Container (CD.backslash.FILE, 21d) of files and Directory in said first format for processing by a first (36) and second (38) interface program; (b) executing said first (36) and second (38) interface program on said first format Container to convert said first format Container (CD.backslash.FILE) into multiple second format original specialized files (MY/FILE/=,21) which restore the data into said original specialized second format.
3. The method of claim 1 wherein said first interface program (36) includes the steps of: (b1) opening said first format Container (CD.backslash.FILE, 21d) to verify it is a Container and to verify its checksum and its security privilege in order to access the files of said first format Container; (b2) locating the Directory information in said first format Container; (b3) locating each file of said first Container, via its directory location, to set up input and output file name pairs in main memory (18); (b4) setting up input and output file names in main memory and setting up parameters for said second interface program (38); (b5) calling said second interface program (MCP.sub.-- WRAPPER).
