`FileOperation`(session)	Provides methods for working on files in a stage.
`PutResult`(source, target, source_size, ...)	Represents the results of uploading a local file to a stage location.
`GetResult`(file, size, status, message)	Represents the results of downloading a file from a stage location to the local file system.
