As far as I can determine, MS Works is needed to open .wps files, or a converter to allow opening with MS Word - but I don't have either program. Is there another way to open such files?

Question: I just got a .wps file in my e-mail, and I can't open it. Answer: You received an orphaned file, created with a program that has long since vanished from stores and most computers' storage.

Open and convert old wps files so they're compatible with all Macs.
