Published File types in Cp6

Hello,

Can you please clarify what the difference is (or what they are used for) between the following published files?  I see these files when I published a non SCORM enabled project in Captivate 6. 

ar folder

assets folder

callees folder

dr folder

vr folder

captivate style sheet

HTML Document with my filename

SWF file with my filename

HTML Document named index

HTML Document named multiscreen

JScript Script file named Project

JScript Script file named standard

thanks!
