gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of the compress utility and other popular archivers. "gzip" is often also used to refer to the gzip file format ...
The following programs in particular can be used to decompress bzip2, .bz2, .zip, and .7z files. Windows. Beginning with Windows XP, a basic decompression program enables decompression of zip files. [2] [3] Among others, the following can be used to decompress bzip2 files. bzip2 (command-line) (from here) is available for free under a BSD license.
7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. [2] 7-Zip has its own archive format called 7z introduced in 2001, [12] but can read and write several others.
lzop is a free software file compression tool which implements the LZO algorithm and is licensed under the GPL. Aimed at being very fast, lzop produces files slightly larger than gzip while only requiring a tenth of the CPU use and only slightly higher memory utilization. [2] lzop is one of the fastest compressors available, [3] a close second ...
compress - original Unix compress executable (gzip'd) Source Code for compress v4.0 (gzip'd sharchives) ZIP File containing a Windows port of the compress utility; source code to the current version of fcompress.c from compress; bit groups alignment - Explanation of bit groups alignment. lzws - New library and CLI, implemented without legacy code.
The Compression Analysis Tool [16] is a Windows application that enables end users to benchmark the performance characteristics of streaming implementations of LZF4, Deflate, ZLIB, GZIP, BZIP2 and LZMA using their own data. It produces measurements and charts with which users can compare the compression speed, decompression speed and ...
Info-ZIP is a set of open-source software to handle ZIP archives.It has been in circulation since 1989. It consists of 4 separately-installable packages: the Zip and UnZip command-line utilities; and WiZ and MacZip, which are graphical user interfaces for archiving programs in Microsoft Windows and classic Mac OS, respectively.
FreeArc uses LZMA, prediction by partial matching, TrueAudio, Tornado and GRzip [7] algorithms with automatic switching by file type. Additionally, it uses filters to further improve compression, including REP (finds repetitions at separations up to 1gb), DICT (dictionary replacements for text), DELTA (improves compression of tables in binary data), BCJ (executables preproccesor) and LZP ...
