`IF EXISTS`关键字可以检测待删除的图空间是否存在，只有存在时，才会删除图空间。

`DROP SPACE`语句不会立刻删除硬盘上对应图空间的目录和文件，请使用`USE`语句指定其他任意图空间，然后执行`SUBMIT JOB COMPACT`。
`DROP SPACE`语句不会立刻删除硬盘上对应图空间的目录和文件。

如需删除无效空间的目录和文件：

1. 在 Storage服务的配置文件中设置`auto_remove_invalid_space=true`。关于 Storage 服务的配置文件的路径，参见 [Storage 服务配置](../../5.configurations-and-logs/1.configurations/4.storage-config.md)。

2. 重启 Storage 服务。具体操作，参见[启动服务](../../4.deployment-and-installation/manage-service.md)。

3. 使用`USE`语句指定其他任意图空间，执行`SUBMIT JOB COMPACT`。
