    It's looking good so far but I'm a bit shocked at the version jump. Going from 4.6x up to 9.01 is a HUGE version jump.

    Just simply brilliant, this is the way how good software should be written. Trouble free and fast, under x64 if you have memory over 4GB, enable large memory pool under options and see how your compression tasts fly. This is the only archiver to scale multiple CPUs so if you have quad core or dual quad core like I do, 4GB compression with encryption are a breeze.

    Switched years ago from WinRAR to this and not regretting any bit. Great tool.

    Perhaps the functionality is more important. Besides, most of the time most people do quick extracts and compresses via explorer where UI is just fine.
