For the mac folks... You can do it a lot faster w/o any third-party apps. Just open Terminal ( Applications -} Utilities -} Terminal ), then type the following: tar -cvzf /Volumes/(path to where you want it saved)/runtime-backup.tar.gz /Volumes/Macintosh HD/Applications/Poser 6/Runtime ...then hit "enter". (hint: hitting the "tab" key while halfway through typing a directory name will auto-complete the name. hitting it twice in rapid succession will give you a list of options based on what you've typed already). Stuffit actually understands opening tar.gz files, so no probs extracting it. Also, there aren't any size restrictions on how big a tarball you can build, so no probs in that direction, either. For Windows? download cygwin to get the same functionality, but the learning curve for using that is a bit steep... /P
