Both Anki2 and Anki folders being updated (Mac)?

I am arranging for periodic backups of my ~/Library/Application Support/Anki2 folder, and noticed that I have an Anki folder as well – I suppose from pre-Anki-2 days. But I see that several files in it were updated today – mostly log files. All the contents of the Anki folder are within QtWebEngine/Default. It’s mostly curiosity that prompts my posting this topic.

One is your user data, the other is non-important files stored by the web toolkit.
