Ahh yes they are _bak , nothing has changed in my file permissions
perhaps if I close the open file too quickly when it is still writing or deleting the _bak it may leave it behind.

Hi shayne, well it doesn't try to delete the previous file until after the new one is completely finished, so I doubt it's a timing thing.

Does it happen every time when saving to a particular folder?

Also does it only happen when using a particular file format?
