I have an old Unixware 2.1.2 server with a bunch of data files with file extension of .IMS.dat and .IDX.dat. I need to retrieve the data from these files, but have no idea what they are or how to access them. I have search,literally, for hours on the internet to get information on what these are and how to access them. ANY clue would be VERY appreciated. I would be using C (not C++), as that is the only compiler available on the machine.
