Im looking at my evolution folder. I see the different folders I created
with my various emails in them.
The inbox file is the largest of them all. Is every single email that I
have received stored in that Inbox file and then messages in the
folders are just linked there?

The reason I as is, Im going to convert this mbox to maildirs and Im
just wondering, do I do it only to inbox or to every folder or what?
