Here’s a sample of how I have the local archive (with a small A) system set up in Mail:
For each year there is a folder, with folders for each month within. Plus one for Sent messages for that year. These are all located in a higher level folder I named Email Archives which resides under On My Mac. Every day or two I manually move messages that are worth saving into these folders - the others get deleted. That keeps the Inbox small while retaining the Messages within the Mail system for fast searching and response. I have messages going back to 2006 kept this way.
So, when I want to really archive these into EagleFiler, I click on a folder for a month, type Command-A and then fn-F1. I believe this is the recommended way to add messages into an EagleFiler library. (Am I Wrong??)
But, what I’ve found is that when I do this, some messages and even some folders are also duplicated by themselves under Records. This is an addition to being saved under the expected and desired folder structure.
I do not see any duplicates in your screenshot. Which are the ones that you were not expecting to see?
Records is a special view that shows all the records in the library, from all the folders (except the trash). So it is normal to see a mailbox there and also see it in its containing folder.
If you have Messages in Records Source checked, Records will also show all the e-mail messages from all the mailboxes.
@Michael_Tsai Just my two cents, but in my opinion the entire Show submenu would be a lot clearer if its subitems were “hoisted” up a level to become individual ordinary menu items in the View menu. These commands do not really have much in common, and Show here is merely a common verb, not a subject as with e.g. Message and PDF; and they are hidden away in a place that I, for one, had never seen before. Users do not squirrel around exploring submenus, so unless it’s very clear what a submenu is going to be about, users are unlikely ever to discover what’s in there. Sure, this would make the View menu longer, but so what? It’s very short at the moment.
