Best converter/archive extractor (.SFW and .NBF) for Sequoia?

I have old CDs, DVDs, and 3.5 inch floppies containing SFW (Seattle Film Works) and NBF archives. I have good DVD and 3.5 floppy external drives. I'm looking at GRAPHICCONVERTER 12 for the SFW files. For the NBF archives I've tried changed the extension to ZIP without success. I've looked a LOT of archive extractors; all seem to have "in app purchases" and no actual price before downloading. Any ideas?

.zip is compression (?) you just can't manually just change the extension hoping it does something.



for media of that sort file ...GraphicConverter is not what comes to mind.
