Poser uses multiple file types for it’s content, DS uses a couple for everything.
Poser Formats
PZ3 = Scene
CR2 = Figures
PZ2 = Pose
FC2 = Expressions
HR2 = Hair
HD2 = Hands
PP2 = Props
LT2 = Lights
CM2 = Cameras
MC6 = Materials (can also be MT5 and PZ2)
DS Formats
DAZ = scenes and anything with a mesh/morph in it
DS = DS1/2 ascii script
DSA = DS3 ascii script
DSB = DS Binary script
DSE = DS Encode Binary script
The DAZ file is similar to Posers PZ3,CR2,HR2 & PP2, while the script files pretty much cover the rest.
With DS4.5 we still only have two types, scripts (DUF & DSA) and assets (DSF), so it’s pretty much a case of stick them where you feel like, if it’s a DUF character preset then that could be your “figure”.
