New *.pem files in /etc/letsencrypt/ every day

Hi,
every day there were four new *.pem files created in
/etc/letsencrypt/csr → 0000_csr-certbot.pem … 0001_csr-certbot.pem and so on
/etc/letsencrypt/keys/ → 0000_key-certbot.pem … 0001_key-certbot.pem and so on
on my server.

I have four virtual domains using letsencrypt - maybe that’s why FOUR new entries are created.

letsencrypt certs are working…

But is that OK? Why do I need all these *.pem?

Thank you, Marko
