BZ2 is a compressed archive file category format. Its creator is Julian Seward, and the full name is Bzip2 Compressed File. The BZ2 format is a free, free command-line utility for compressing data. It is open source. For the effective implementation of its function uses the Burrows-Wheeler algorithm. Data compression in this format is much more efficient than the more common gzip or ZIP utilities do. However, this is slower. Compressed files of this format are most often used on Unix operating systems.
ZIP is one of the most popular and common archive or compressed file formats. The full name is Zipped File and the original name is Compressed ZIP archive file. The ZIP extension, which is used to package or compress files, was developed back in 1989. Its creator was Phil Katz, founder of PKWARE Corporation. Initially, the format was used in the PKZIP program, but now there are many other utilities to work with ZIP files. The ZIP format uses a standard compression type for compression, in which all individual files in the archive are compressed separately.
