If you're tired of being bugged by WinZip to upgrade or register and don't mind using something slightly different, then ALZip is an excellent solution.

AlZip is compatible with all ZIP and compressed file types and best of all, it's completely free for home use so there's no annoying nag screen or usage period to worry about. But much more than that, AlZip allows you to choose which program you want to open a certain file with rather than autoselect one for you or open it as generic Windows file. It's also a good option for unzipping files that have been downloaded from eMule or other P2P networks because it scans them for malware or viruses before opening them. The one thing that strikes you about this program though is how easy it is to use - you're grandma could probably unzip files with this program easily. It takes you through the unzipping process gently and doesn't hide decompressed files in some inconvenient location like some programs do. It also doesn't require any plugins or add ons to enhance its functionality or deal with certain file times - it's all in the program anyway. The latest release is ultra fast and they've implemented a new update and restore option for repeated tasks.

For a comprehensive, easy to use and powerful decompression tool, ALZip is all you need to banish those zipper blues.
