Canonical list of ~/.local/share/akonadi directories and files

[Jerome Yuzyk]

KDE-something on Fedora 25

I upgraded from Fedora 20 to 25, release by release. Now I'm doing some 
cleanup of ~/.local/share/akonadi and I'dlike to know what directories and 
files I should have, so I can clear out what I shouldn't. 

For example, I have a akonadi.db with a Modify time of several years ago. I 
also have a few directories like db_misc and db_data/mysql with the same 
time.

So is there a list of what I should have?
