A self-extracting archive created using 7-Zip. A self-extracting archive (SFX or SEA) is a computer executable program which combines compressed data in an archive file with machine-executable code to extract the information. Running on a compatible operating system, it does not need a suitable extractor in the target computer to extract the data.
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.
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.

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. It ...
In computing, Deflate (stylized as DEFLATE, and also called Flate [1] [2]) is a lossless data compression file format that uses a combination of LZ77 and Huffman coding.It was designed by Phil Katz, for version 2 of his PKZIP archiving tool.
UPX uses a data compression algorithm called UCL, [5] which is an open-source implementation of portions of the proprietary NRV (Not Really Vanished) [6] algorithm. [2]UCL has been designed to be simple enough that a decompressor can be implemented in just a few hundred bytes of code.
