7z Mac file technical details

7z files can be multi-volume archives that can be converted to one file after the archive has been transferred by volume. It should be noted that the 7z format does not support the storage of file system access rights (UNIX ACL or NTFG), i.e. using the 7z format for backup and archiving can be problematic due to the ability to bypass protection. Besides that, 7z format allows you to reach 4–25% better compression ratio than the ZIP format. 7z is considered to be “protected from obsolescence” because it is supported by a large number of new 7z extractor apps. Currently, 7z is an open-source extension available for public use since 2008.

Compression methods that support 7z files are LZMA, PPMD, BCJ, BZip2 and Deflate. The open architecture allows you to put methods of compression, conversion, and encryption in the queue. This type of files is used to store and send/receive very large files or their groups. Nevertheless, files with the extension .7z can be run only by some 7z Mac, Windows, Android, Linux programs. It is possible that .7z are data files, not documents or media, which means that they are not intended to be viewed at all.
