In the good old days, we need RAR so we could split the file into multiple floppy disk, now simply known as the Save Icon. We also prefer it over zip simply due to better compression ratio. I wonder do we still need these trade offs or we could simply go back to Zip or other self extracting compression format. I don't think RAR is even natively supported on Mac.
Since RAR and 7-zip is supported by Windows out of the box these days, I can not think of much scenarios where you would benefit from WinRAR in a way you'd be willing to spend money for.
