Well winrar is a program you have to install and you can download this from their site. I would just do a search for this.
right click the .rar and select extract files....
i think its extract files but i havent used winrar in ages
Its best to use StuffIt expander to decompress the files that's the decompresser which works best for me
You have to uncompressed the files rar is a compression format.
Oh I already have winrar, what do I do from there?
And how might you do that?
