default save folder

[Pau <vim.unix@xxxxxxxxxxxxxx>]

Hello,

is it possible to tell mutt where to save things such as attachments?

I would like to define a folder and tell mutt to automatically prompt
me to that folder everytime I want to save something.

The same for the addresses. Everytime I define a new alias, I would
like that mutt knows where all addresses are. How can I predefine that
file in muttrc?

Thanks

Pau
