@J-Lawrence If you don't want to contribute something productive in this thread, then fine. But please don't post any 'BETA' nonsense here.
there is also a 7zip fork called easy 7zip its a bit more userfriendly you can get it from e7z(dot)org
Current beta is good, as usual. .7z format rocks as does the software, which each 'beta' could count as a final release, as they are pretty stable as these are (no problems handling anything).
I've been used 7-zip for years and never been reported a single run issue. What makes it perfect is its free and multi-platform supports. The size of installer is not large. And PC reports no overload, a lightweight tool I guess. Totally love it. If you've been used other zip software, maybe it's time to try a new one, I mean, just have a try on 7-zip. It'll be a great choice.
