Empty files created when I Export?

If I import a folder with three text files and then export the same thing I get my folder with three files back plus an empty file which is supposed to represent the contents of the folder. But I do not have any text contents in the folder so why is it created?

If a completely blank RTFD file is created, then this is a bug - thanks for bringing it to my attention. I haven’t got time to test it out right now (this week is moving house week), but I have added it to the list of things to look at for 1.1.
