is a free Gui for 7-zip. It adds a few doodads like icons in the 7-zip Explorer context menus, and an easy to use File manager etc..
I was waiting for it to update to the new 16.x releases of 7-zip. According to the home page it now contains 7-zip 16.04.
If you like 7-zip just the way it is there's no need for the Gui. But I like some of the things the author has done. Simple enhancements that do not break anything but make 7-zip more fun to use.
Edit: Also when installing newer versions of 7-zip in the future you can overwrite the old one and Easy 7-Zip's context menu icons etc.. will still be there. I was using 16.03 and 16.04 with it. But I figured I would uninstall 7-zip and install Easy 7-zip combined package just to be pedantic.
