I would like to ask to developers of 7z if they plan to make some work on visual interface? 7z is powerfull tool, I have to say, but without common visual interface like winrar, winace, winzip...
The 7-ZIP "interface" (2 panels) is good !!!
But feel free to pay for or search a crack for WINEZIP,
WINERAR, WINEACE, ... :-D
Don't forget to enjoy the built-in spyware :-D :-D
