I'd like also to share the best archiver for Windows 7.
I think, it's
B1 Free Archiver.
Why?
- Because it's free (you don't need to pay anything);
- simple to use (does the same task as popular archivers, but you will not waste your time searching which button to click on);
- has such great tutorials at the site. Check this one about opening .rar files in a click:
