When you have selected the export quiz form the main drop down menu, the files will be exported into the backup directory you have set-up. All files form the quiz (pictures and sound files) will be exported together with a backup of the questions to that quiz.

Additionally a word file will have been created to allow printing of the questions for that quiz. Each question is formatted correctly, and a place holder for the pictures or sound files, that can then be added into the document to replace the place holders.
