Ok I have now tried with two other files, 1 which was 8k in size and  
1 which was 11MB in size. Both were fetched without any TLS issues -  
therefore it appears that BB has an issue restoring single files over  
a certain size. The file I am trying to restore is 3.5GB is there a  
limit anywhere ?

Kind Regards
