I don't use kmail on my Ubuntu anymore. I use Thunderbird now.

still I have this 1.6GB large file 

~/.local/share/akonadi/file_db_data

I only guess, it is so large, cause my IMAP folder is about that size and It was created, when I tried out kmail.

Is that file needed for anything else than kmail?

If I would remove the whole akonadi-server with 

apt-get remove --purge kmail akonadi-server

would that delete anything I could still use although I don't use KDE anymore?

For example, I still use krusader and some passwords stored there seem to come from the kde-wallet.

In general: things that reside in ~/.local/ in a sub-directory belong to the software that the directory is named after. file_db_data belongs to akonadi so deleting the file will affect akonadi. If you do not care about that anymore it is safe to delete both the file and the directory.

This:

sudo apt-get remove --purge kmail akonadi-server

should also remove that directory and the file. It will not delete krusader.

The Akonadi database is NOT your MAIN data storage. Even if it gets destroyed, removed, your data is still safe.

However, if you'll still use Akonadis functionality and you really need the disk space, I would instead recommend to uncouple unneeded data sources (IMAP mail folders etc) and execute this command: akonadictl vacuum
