Did You Know?

By default, 7-Zip generates 7z format archives with a .7z extension. Each generated file can have multiple directories and files. As a container format, security or size reduction are achieved using a stacked combination of filters. These can consist of pre-processors, compression algorithms, and encryption filters.
