Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zip compresses to zip format 2-10% better than most of other zip compatible programs.

This file-archive tool is simple to use but offers little new functionality to compress or extract files, and suffers from some occasional stability issues. Alpha ZIP's simple interface offers oversized buttons to open or create ZIP archives, and both processes are easy to follow. The program lets you view folder contents and launch files in an existing zipped folder and supports drag and drop to easily add files to a new archive. You'll also find an AlphaZip folder on the Windows Explorer's context menu. You can easily choose compression options, create a self-extraction tool, and, with the registered version, apply password protection to an archive. Though we liked the simplicity of this application, the only extra feature it offered was the ability to test an archive's validity, and we encountered some errors during testing before the archive process could complete. You'll have 20 days to evaluate the trial version. Despite this archiving utility's ease of use, the issues we encountered make it hard to recommend, and users should look elsewhere for a more stable alternative to manage zipped files.
