RocketMQ提示磁盘空间已满，如何处理?

按照官网的quick-start部署，name server和broker启动成功，但执行“.\bin\tools.cmd org.apache.rocketmq.example.quickstart.Producer”时提示如下错误：

org.apache.rocketmq.client.exception.MQClientException: Send [3] times, still failed, cost [9]ms, Topic: TopicTest, BrokersSent: [DESKTOP-0TR4N4Q, DESKTOP-0TR4N4Q, DESKTOP-0TR4N4Q]

按官方要求磁盘空间需要4G以上，但我最低的磁盘分区剩余空间为6.27G,C盘剩余空间为14G，部署RocketMQ的F盘剩余空间为22G,请问该问题如何处理?

RocketMQ版本为4.9.0
