.EPD File Extension

I used Express Publisher years ago on my first dos based computer. I still have some files I need to convert. Express Publisher is similar to Microsoft Publishing. The extensions are different so you cannot open EPD extension without the proper software. I cannot find any software that will open EPD extension. I have a large document that I would love to retrieve instead of retyping it.

I also used Express Publisher during the 1990s and now have a need to reopen the files, but no longer have a working Express Publisher. Can anyone help with converting, or opening these in a more up to date program, e.g. Word, or Framemaker?
