James, Ignore the .RSR files - they are not your problem. The .rsr files (and/or .png files, depending on which version of Poser you are using) are the files that provide the "thumbnails" when you open up one of the libraries in Poser. Without them you just get the "shrugging man". The PZ3 files contain complete scenes and can go anywhere you want (Personally I use a folder called "+++MySaves" under the Poser directory; the "+++" prefix is to kep the file near the top of the list when the "Save As" dialogue opens.
