I'm not sure anyone can follow what you do with those files on one of your "random drives". OK, I can't and that's just me, ignore it.

Your details are confusing. Public keys are this: https://learnmeabitcoin.com/beginners/guide/public-keys/
I've no good explanation why someone not-so-Bitcoin-technical would've a folder with a "series of public keys". Is this folder in proximity of some wallet related folders. Do you mind telling its name? Not sure if this would shed some light into this mystery.

Does this Armory wallet screenshot look similar to this one?

I can't speak for the integrity of users whom you send possibly pictures of wallet recovery details. You should be careful whom you can trust with such details.

I also don't get why you speak of PGP keys in the context of wallets. You mentioned PGP keys already earlier which confused at least me a bit, but I didn't see it as important.

Every now and then new things pop up. Next is "keygen software". I would associate this with the warez scene, keygens being usually small pieces of software to generate serial keys for some software which needs specific serial keys to activate/license it.

This is no rant, I'm just confused by your story. Consider to omit unnecessary personal details of your family and how you spend your time. I don't see how this relates to your topic here. You may think it's nice for the context, but I find it rather off-topic and distracting. I don't know how others think of it.

Personally I find a lot of recovery related topics quite interesting because many have good challenges and things to learn from. Enough for now...
