But WinRAR isn't free. It's shareware with a nagscreen (although its running unlimited). And the author asked for a completely free software I think.
You want to know about nag-ware, ask my wife. Nag-nag-nag-nag-nag... although I may be thinking about something else entirely. 😉
@Vlad_the_Bad I feel your pain brother! I use 7Zip myself because it is free and is rock solid.
