Missing satoshi emails?

So i came across a hard drive in an estate sale some time ago. I did notice these emails but thought nothing of it.

I was curious so went on nakamotinstute. Org and other sites and compared. While some emails on the drive did match, a lot of other did not.

There are also an unsent and trash files that appear to have data but cannot be viewed as they are in a .msf file format.

Maybe these are something? Maybe not?
