A directory is placed at the end of a ZIP file. This identifies what files are in the ZIP and identifies where in the ZIP that file is located. This allows ZIP readers to load the list of files without reading the entire ZIP archive. ZIP archives can also include extra data that is not related to the ZIP archive.
Linux, macOS, Windows Genozip, a compressor for genomic file formats such as FASTQ, BAM, VCF and others. [4].gz application/gzip [5] gzip: Unix-like GNU Zip, the primary compression format used by Unix-like systems. The compression algorithm is Deflate, which combines LZSS with Huffman coding. .lz application/x-lzip lzip: Unix-like
XZ Utils can compress and decompress the xz and lzma file formats. Since the LZMA format has been considered legacy, [2] XZ Utils by default compresses to xz.. In most cases, xz achieves higher compression rates than alternatives like zip, [3] gzip and bzip2.
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.
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.
In popular Linux distributions, lzip can usually be installed from official package repositories. [ 5 ] [ 6 ] [ 7 ] Cygwin offers lzip as a maintained optional package (Archive category of its setup installer), and its GNU tar utility program has support for .lz archives (with --lzip option for creation).
gzip is a file format and a software application used for file compression and decompression.The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from which the "g" of gzip is derived).
The 7-Zip implementation uses several variants of hash chains, binary trees and Patricia trees as the basis for its dictionary search algorithm. In addition to LZMA, the SDK and 7-Zip also implements multiple preprocessing filters intended to improve compression, ranging from simple delta encoding (for images) and BCJ for executable code.
