Despite the growth of computer storage capacity and network speeds, data compression remains an essential tool for storing and transmitting ever-larger collections of data. The .zip format is designed for cross-platform data exchange and efficient data storage for a set of related files; combining 85% to 95% average data compression, file management, and data encryption within a portable archive format. A ZIP file is a package containing one or more files, usually compressed and sometimes encrypted.

A big advantage of the industry standard .zip format is the wide adoption of zip tools and processes across virtually all computing platforms, and its ease of use for end-users of all technical competency levels. Practically any one who uses a computer is familiar with Zip files. Making it easier to implement efficient and secure exchange of files within the enterprise and beyond.

There is a trade-off between the time and memory that compression algorithms require and the compression that they achieve. ZIP/390 provides options for balancing compression time and overhead with compression rate to achieve the optimum benefit on a case by case basis. ZIP/390 also takes advantage of latest Mainframe hardware technologies for greatly reducing the time and cost of compression on this platform.
