Let me get this right. An Alpha version of a Zip program makes it onto the front page of Neowin during the week of Windows 8 launch, the announcement of the iPad mini and a shed load of other stuff!!!

7-zip are obviously paying Neowin to have this on the front page

No money from 7-zip. It was a mistake and now is fixed.

Or because it is so great that the author of this post wants the world to know it.
Compressed 7z files always have lowest size compared to RAR, Ace or Zip.

This is the software section, Ipad mini is hardware.

Ah crap, forgot the sarcasm tag.

I am not sure if it is a wise decision to offer the ALPHA version of a program for download? After all, it is "alpha" for a reason and hasn't even reached BETA state yet, so, linking it here without any disclaimers makes you pretty much responsible for any kind of problems that may pop up on a "not-so-tech-educated user's computer after install ... !

7-zip has been in "Alpha" for two years now. It never gave me a problem but its like the authors want no responsibility if your files get corrupted. They need to get serious.

7-Zip is actually the best file archiver ever, with the maximum compression and it is also free.

Give it a try, people; and you will never go back to SHAREWARE WinRAR or BLOATWARE WinZip anymore.

Pretty much agree with you on this one.

May not have EVERYTHING, but it's the only utility of this type I've NEVER had a problem with. That's counting alph, beta and what ever other version they've ever released.

It still needs some things that WinRAR offers. Things like extract path auto-complete and path history. If they add those features I see no reason not to move to the free 7-Zip.

If you don't need advanced features for complicated scenarios, definitely the leading file archiver...

Yet release schedules should keep up a little - at least once a year new release cycle would be great...
