Snow, I'm afraid you can't use WW if you don't have Propack, P5 or P6 since it's a python-based app that works from inside Poser, not stand-alone. The only thing that .dat files help you with is that in order to analyze the clothing before you convert it you have to have the figure it was meant for. So, if someone else analyzes it for you and gives you the .dat file all you would need to buy is the clothing item and then just convert it to whatever figure you want (provided it's a supported one). For example, I don't have nefti's Toon Gal but I like one of her outfits, someone who has the gal and the outfit analyzes it for me, I buy just the clothes and convert to Aiko. Hope this helps.
