The NIO connector can access the local or mounted file systems, as well as different in-memory file systems.\
This is probably the easiest way to start, especially for prototyping and testing purposes. For productive use, the other file systems are preferred.

```java
NioFileSystem fileSystem = NioFileSystem.New();
EmbeddedStorage.start(fileSystem.ensureDirectoryPath("path", "to", "storage"));
```
