FilePathZip2

java.lang.Object
- org.h2.store.fs.FilePath
- - org.h2.dev.fs.FilePathZip2

```
public class FilePathZip2
extends FilePath
```
This is a read-only file system that allows to access databases stored in a .zip or .jar file. The problem of this file system is that data is always accessed as a stream. This implementation allows to stack file systems.
