reducing disk space consumption

Hi, I am using DSE 4.8.4 On one node, disk space is low where: 42G /var/lib/cassandra/data/usertable/data-0abea7f0cf9211e5a355bf8dafbfa99c Using CLI, I dropped keyspace usertable but the data dir above still consumes 42G. What action would free this part of disk (I don't need the data) ?
