[Trying to extract data from "sparky 2000" data files]

I am trying to extract data from a old software called sparky 2000. It is a dos based program running on windows 98. I do not have access to the actual software i only got a copy of the data files. I can view the *.dat files in notepad but there is indexing issues with the files and I see file extensions like DXA,DXB,DXC,DXD along with the data file *.DAT .
Does anyone know in the software if you can extract the data to a delimited file or does anyone know of a way to convert these files to a readable format?

Thanks for any help
