Can I use 7-Zip in a commercial organization? Yes, 7-Zip is free software. You can use it on any computer. How can I set file associations to 7-Zip in Windows 7 and Windows Vista? You must run 7-Zip File Manager in administrator mode. Right-click the icon of 7-Zip File Manager, and then click Run as administrator. Then you can change file associations and some other options. Why 7z archives created by new version of 7-Zip can be larger than archives created by old version of 7-Zip? New versions of 7-Zip (starting from version 15.06) use another file sorting order by default for solid 7z archives. Old version of 7-Zip (before version 15.06) used file sorting «by type» («by extension»). Parameters field in «Add to archive» window, (or -mqs switch for command line version). You can get big difference in compression ratio for different sorting methods, if dictionary size is smaller than total size of files.

If there are similar files in different folders, the sorting «by type» can provide better compression ratio in some cases. Note that sorting «by type» has some drawbacks. For example, NTFS volumes use sorting order «by name», so if an archive uses another sorting, then the speed of some operations for files with unusual order can fall on HDD devices (HDDs have low speed for «seek» operations). Increase dictionary size. It can help when ‘qs’ is not used. Specify ‘qs’ in Parameters field (or use -mqs switch for command line version). If you think that unusual file order is not problem for you, and if better compression ratio with small dictionary is more important for you, use ‘qs’ mode. Why can’t 7-Zip open some ZIP archives? In 99% of these cases it means that the archive contains incorrect headers. Other ZIP programs can open some archives with incorrect headers, since these programs just ignore errors.
