Why can I use a Command File Output from a CloudRunner on a GroundRunner, but not the opposite?

Question 
File Command outputs generated by a CloudRunner can be leveraged by the GroundRunner. How about using output that is generated by GroundRunner? Can this output be leveraged by the CloudRunner? 

Answer
File Command outputs generated by the CloudRunner can indeed always be downloaded by a GroundRunner. OneCloud however does not allow File Command outputs generated by the GroundRunner to be downloaded by a CloudRunner. This is to ensure that the on-premises data remains secure and does not inadvertently leaves the on-premises environment.
