File names
And as ANY long time Shopbotter will tell you, do NOT name your files "test". You have NO idea just HOW MANY files you will keep finding on flash drives, CD,s , DVD's (even floppies too...) with the SAME name. I have been to shops where some 'Botters have VOLUMES starting from "test 1" to "test 2,354,567,987" etc. !!! The header writer MAY help to bail you out, but as it has been suggested a good naming protocol will make your life SO much better....
