Batch Convert Word Perfect Files to PDF

I have Word Perfect 8 on Windows 10. I have something like 7000 Word Perfect files on my computer in probably hundreds of folders. In a fantasy world, with a click of a mouse, I would like to convert every Word Perfect document to a PDF document, that would be placed next to every Word Perfect document in every folder.

Closer to real life, I would like to be able to, say, open a folder with 70 documents, 50 of which are Word Perfect documents, highlight the 50 documents, have them converted to PDF files (that can later be altered), and save those 50 PDF documents in the same folder. Is this expecting too much?

At present, I could individually open each wpd file, choose "Publish to PDF",and convert that individual wpd file to PDF with the included Adobe Acrobat DC software. Also included on my computer is "Foxit Phantom" converter, but nothing about this software works, not even on individual documents. It just says that it crashed, asks to send a report, promises to respond to me, and never does.
