The LZ4 algorithm aims to provide a good trade-off between speed and compression ratio. Typically, it has a smaller (i.e., worse) compression ratio than the similar LZO algorithm, which in turn is worse than algorithms like DEFLATE.
lzip is a free, command-line tool for the compression of data; it employs the Lempel–Ziv–Markov chain algorithm (LZMA) with a user interface that is familiar to users of usual Unix compression tools, such as gzip and bzip2.
[citation needed] Others (like 7-Zip or RAR) can create self-extracting archives as regular executables in ELF format. [ citation needed ] One of the early examples of self-extracting archives is the Unix shar archive, which combined a number of text files into a shell script that recreated their original content after being executed.
An archive format designed for the Apple II series of computers. The canonical implementation is ShrinkIt, which can operate on disk images as well as files. Preferred compression algorithm is a combination of RLE and 12-bit LZW. Archives can be manipulated with the command-line NuLib tool, or the Windows-based CiderPress. .sit application/x ...
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.
On newer formats such as 7-zip, there is a solid block size option that allows for the concatenated data block to be split into individually-compressed smaller blocks, so that only a limited amount of data in the block must be processed in order to extract one file. Parameters control the maximum solid block window size, the number of files in ...
