`void`	`clearContainer(String container)` Empty the container of its content (files and subdirectories), but doesn't delete the container itself
`void`	`clearContainer(String container, ListContainerOptions options)` Like `clearContainer(String)` except you can use options to do things like recursive deletes, or clear at a different path than root.

`void`	`deleteDirectory(String container, String directory)` Deletes a folder or a directory marker depending on the service
`boolean`	`directoryExists(String container, String directory)` Determines if a directory exists
`Iterable<String>`	`getAllContainerNames()` Return an iterator that reports all the containers under base path
`Iterable<String>`	`getBlobKeysInsideContainer(String container)` Returns all the blobs key inside a container
`File`	`getFileForBlobKey(String container, String key)` Returns a `File` object that links to the blob
`Blob`	`newBlob(String name)` Creates a new blob
