disk space usage overquota for high mysql disk space

[r3cocina]

Hi to all! My SQL database has only 100MB.
How can I clean my sql disk space? I have only a wiki on my account.
Commands? Querys (I'm not SuperSu)? Steps? I attach images
Is mysql binlogging? If yes how to change it on x10 server?
Thanks
