How to have more verbose logs for mysqld startup

I have installed MySQL 8.0.17 via the official installer for Windows.

I am starting MySQL like this

mysqld --log-error-verbosity=3 
         --console 
         --defaults-file='c:/mysql/etc/my.cnf' 
         --bind-address=127.0.0.1

I have configured in my.cnf these directories

datadir="C:/mysql/data/"
general_log_file="C:/mysql/log/mysql-general.log"
slow_query_log_file="C:/mysql/log/mysql-slow.log"
log-error="C:/Users/mysql/log/mysql-err.log"
log-bin="c:/Users/mysql/log/mysql-bin.log"

and please note that c:/mysql is created by me for the logs, data-directory and configuration file. The installer has installed MySQL to some other directory.

After starting mysqld with above line I get this response:

I am pretty sure that I got the server running the last time I tried (which was also the first time for me). However I have just CTRL-C the server in the console window when I was done. Is it possible that the data-directory got corrupted / or needs some cleaning? How can I get more verbose logs? E.g. I would like to get verification that the correct configuration file is picked up and the data-directory is really the one I thought I have configured.

The option

–defaults-file=’c:/mysql/etc/my.cnf’

is one of the options that must be given as the first argument. This solved my problem but does not answer the question how to get more verbose logging…
