[opensuse] getting rid of snapshots

Hi all, I want to get rid of snapshots, because they filled my / volume. I ran snapper delete, and limited the number of snapshots to 1, and disabled snapper in yast2 config. I got only very little space back. If I understood well what I read to physically remove files from /.snaphots, I would need to run suse.de-snapper and btrfs-balance found in /etc/cron.daily and cron.weekly directories. But I do not have any of them. Where are they? I use Tumbleweed with KDE. Thanks, Albert
