Thanks all.  I'm able to now unzip zipfiles with rar files in them.  How do I now get upload them to Poser for use?  I'm also downloading free OBJ files from sites like Turbosquid.  The OBJ files import into Poser with the Import Wavefront OBJ command from the file tab.  Is there a way to create a runtime and add these files to my Poser 11 library?  It would be nice to search my library find the file and click on it to load it into Poser.  Thanks.
