That is where MM will save attachments that you explicitly save.

I believe that Benny has explained it here but5 I think you're correct: 
it's not really documented.

I believe so and that is my recollection of Benny's discussion of the 
Attachments folder.

I think not, but I could be wrong.

I certainly hope not. If it does, I am likely to be the metaphorical 
canary in the coal mine... I have deleted many files out of Attachments 
over ~5 years and have seen no problems that I can associate to that 
practice.

That's what I do. I've seen no trouble and no indication that MM ever 
purges Attachments.
