Fair enough Kuroyume. I appreciate that writing the routine would be relatively simple for Poser compressed files as it's using a common routine to do the compression. I just don't see it as such an issue that Studio doesn't support it. That's obviously coloured by own thoughts on the matter and that no files I've ever downloaded or purchased have been pz compressed so it's not like it's commonly used for much of anything. It's perhaps something to mention to Daz, all they need to do is incorporate a zip routine into the software as that will uncompress the PP/P5 files that are packed. Thing being here is, how long will that even be important? I'm sorry, not knocking what you say but I just don't see it as particularly important. As regards proprietary formats, that's not what I meant. I was more inclined to find a program like Studio, C4D etc that opened "zip" files so you could access the content live inside the app. After all, the pz format used by Poser is just a "zip". It can be opened by winrar, winace, winzip, etc etc. I don't personally own anything that can open a zip file, import the item into the workspace and let me work on it. It's necessary to unzip the stuff first, then load it to the workspace.
