It's not really safe to unzip your downloads directly into Poser. You never know exactly how things were setup. The downloads might have been zipped with folder options, or everything might have been in one folder. The downloads might have been put in the wrong folders, or the wrong structure. The image on the left represents the Default Metacreations installation. Some Poser installations begin with Curious Labs. If you're organizing a zip download, you can't start with either one, because it would be thrown off if you did. Many zipped downloads start with Runtime and duplicate the Poser file structure from there. In the second image, someone started with Poser 4 as the first folder, you entire installation will be screwed up. Files will go where they don't belong. In the third image, someone used a lower case "r" in Runtime. That won't work either. In the end you really need to unzip to a temporary folder and look over your download. You can always copy from there. Most of us prefer to reorganize things when we can.
