BT Cloud keels creating .bak files

[MCB]

Every time I update a file on my laptop BT Cloud backs it up into the Cloud but it also makes a .bak version of the file as well. What can I do to stop this?

Sorry, I've sorted the problem. I had just updated my Office suite and the spreadsheet programme was creating default .bak copies. I have now turned that off!
