Editor’s Review

Most people first discover 7-Zip because they’ve downloaded an archive file with the file extension RAR, and their computer won’t open it. However, once they install 7-Zip, they quickly realize its capabilities go far beyond just a RAR opener.

With this handy tool, users can open nearly any archive file format, and create archives of their own, usually at a far more data-efficient means than with their computer’s proprietary archiving utility. After using 7-Zip for a few days, and really putting it through the paces, we quickly realized why this is the most popular file compression software; it did everything we asked it to in no time, and the interface was simple to navigate. The archiving options were all easy to use, and regardless of the format of the archive (ZIP, RAR, 7Z) they all seemed to be highly space-efficient.
