I just checked the Poser Forum FAQ (which hasn't been updated in over a year), and yours is the first question. Unfortunately, it needs to be updated to say that you can put those morph.obj files anywhere, but to avoid going insane, organize them in a folder called "morphs" or similar, at the top level of your Poser folder. We have 9 honchos serving as forum wranglers here - maybe they can have a "lumberjack match" to determine who has to update the FAQ
