CCZip is a fast, efficient and powerful ZIP utility. It provides intuitive zipping, unzipping, disk spanning, SFX, and encoding. More importantly, it provides built-in tools to work with archive files without unzipping. CCZip allows you to do inter-application drag and drop (just like in the explorer). With CCZip you can edit files inside a zip in "one step" and you can view images with an internal image viewer that supports several popular image formats.
