File types in N360 backup data set

Norton has an eccentric interface for specifying what should be backed up. Is there anywhere that fully defines what extensions they are using for their various "types" - for example, what are they assuming email file type or extension is? Many of us have extensions not covered by their list. What if I want ALL files in a folder backed up regardless of filetype? (Where is the good old *.*?)

Curious, what Extension - File Type is not covered by their list?  
ALL files in a folder.  Create New Set with path to that folder.  for example:  C:\Users\User\Desktop
