I don't know about RAR, but Joke gave you a reference to an answer about this in her answer, click on it and see if it makes sense to you. Bringing you back to the top. Hugs, Marji

you will need a software program that will "expand" rar files. They are compression files like zip files, but not all programs will "unzip" them. I use two different types of programs and someone else also mentioned one they use. I really like The extractor 1.4.1. It has lots of extras that work for me. I've attached the download link to CNET if you are interested.
