Exactly what you get from Takeout varies from service to service; for email you get an MBOX-format mailbox file (that you can then import into a desktop email client of your choice).

Really? mbox, not maildir? That must be insanely huge.

I pulled mine recently and it was about 3.5GB with ~115k items (chat messages are included). Also pulled my wife's - 217k items @6GB.

[dmd]

Right. So, maildir format then, not mbox.

[cdubzzz]

It is actually mbox. I should have provided more detailed numbers - in my Takeout file, for example, there are 91,360 chat messages and only 23,407 email messages .

[dmd]

So there's 23407 email messages but only one file containing all of them?

[cdubzzz]

Yep! All messages are in a single mbox file and it's 3.2GB.
