Yes. Only the 'data' and 'Runtime' folder. But start to read the manual before you ask the next question about installing DSON:

And keep in mind that you need DAZ Studio for creating your own Poser companion files! Because you can and will convert clothes from M3/V3 or M4/V4 to Genesis (M5/V5) or Genesis 2 (M6/V6) in a few easy steps. But you don't need DS's 'Camera Presets' etc. for that. :-)
