Fast download and it worked out of the cloud-box. I was happy with how well it worked considering it's free. A++ Highly Recommended

7-Zip is a powerhouse of usability, replacing your normal zip archiver and your ISO disc mounter. The software is free and works great. It works automatically (if you let it manage your zip files). But its interface is sparse and so is documentation. I couldn't imagine suggesting this to a beginner. Although the program works great, it is not good at guiding you into actions (i.e. add file, save archive). You're often left wondering "now what?". Nevertheless, 7-Zip is great software and highly suggested for all Windows users!

7zip Works like a charm with most archive formats on Win7. It even works when I associate Mozilla add-on files (*.jar & *.xpi) which saves me having to rename them to *.zip, open with Win7, close with Win7, rename back to their previous name. Free is nice.
