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.

  cdubz@professor-farnsworth ~/data $ du -h Mail-chris.mbox 
  3.2G	Mail-chris.mbox

[dmd]

Wow. I stand corrected and that's awful. Yet another reason to use gmvault!

[icebraining]

Why it awful? As an archive, seems decent.

[dmd]

(1) inconsistent escaping rules (dealing with the literal string \nFrom)

(2) easy to corrupt

Worth noting that Google provides some Python sample code for parsing the file which works great.
