download WinRAR, it'll open .rar's and, regardless of what the website says, you can actually keep using it after the "trial". After the trial ends there's a little pop up that appears but you can just close it out and still use it.

loli
download winrar, i won't give you a link, google it. use it to extract your .rar file.  It says 30day trial period, but it works forever, ignore that.

You can use WinRAR, or you can use 7zip (my favorite).
The cool thing about 7zip is it can create and open .7z archives, and you are likely to come
across a few of those.
