I am investigating the feasibility of a project that would read an existing database that is available on optical disk (High Sierra format) for computers running ms-dos. I want it to run on a mac. Because the database is so large, (otherwise they wouldn't have put it on optical disk, would they?) I can't just copy the files onto a hard drive using something like apple file exchange. I presume I need a program/routine that makes a dos-formatted optical disk appear to be an "on-line" mac disk, or something that directly reads and interprets the dos file-system and handles all of the file-system functions. Is this commonly done and/or are there libraries/programs that handle this? If so, what are they? A final question. Just out of curiosity, did the ms-dos file-system have to be tweaked to deal with the large files you can create on an optical, or was it able to handle it in its original design?
