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). Version 0.1 was first publicly released ...
zlib (/ ˈ z iː l ɪ b / or "zeta-lib", / ˈ z iː t ə ˌ l ɪ b /) [2] [3] is a software library used for data compression as well as a data format. [4] zlib was written by Jean-loup Gailly and Mark Adler and is an abstraction of the DEFLATE compression algorithm used in their gzip file compression program. zlib is also a crucial component of many software platforms, including Linux, macOS ...
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.
B1 Free Archiver supports opening most popular archive formats (such as B1, ZIP, RAR, 7z, GZIP, TAR.GZ, TAR.BZ2 and ISO) but can create only .b1 and .zip archives. [6] The utility can also create split archives which consist of several parts each of specified size [7] and password-protected archives, encrypted with 256 bit AES algorithm. [8]
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. It is developed by Igor Pavlov and was first released in 1999.
The Linux kernel has included Zstandard since November 2017 (version 4.14) as a compression method for the btrfs and squashfs filesystems. [16] [17] [18]In 2017, Allan Jude integrated Zstandard into the FreeBSD kernel, [19] and it was subsequently integrated as a compressor option for core dumps (both user programs and kernel panics).
.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 An alternate LZMA algorithm implementation, with support for checksums and ident bytes. .lz4 LZ4: Unix-like
Decompression speed is higher than bzip2, but lower than gzip. Compression can be much slower than gzip, and is slower than bzip2 for high levels of compression, and is most useful when a compressed file will be used many times. [4] [5] XZ Utils consists of two major components: xz, the command-line compressor and decompressor (analogous to gzip)
