When using the uploadFile method, it uses internally the method deposit from class UploadFile. Method deposit returns a DepositReceipt that contains the result of the operation, for example the identifier of the file that you uploaded, but the method uploadFile does not return anything. This makes impossible to keep manipulating the file for example for metadata addition because you are not returning the identification.

¿Could you please explain if this is the intentional design? ¿Is there a possible workaround to obtain the id of the file that you updated with the uploadFile method?

If not I will raise another pull request to fix this or add another method that has this behaviour.
