2. 7-Zip - Wikipedia

   en.wikipedia.org/wiki/7-Zip

   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.

4. Solid compression - Wikipedia

   en.wikipedia.org/wiki/Solid_compression

   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 ...

   RPM files consist of metadata concatenated with (usually) a cpio archive. Newer RPM systems also support other archives, as cpio is becoming obsolete. cpio is also used with initramfs. .shar application/x-shar Shell archive: Unix-like A self-extracting archive that uses the Bourne shell (sh). .LBR .LBR: CP/M DOS A system for storing multiple files.

6. Lempel–Ziv–Markov chain algorithm - Wikipedia

   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.

7. Self-extracting archive - Wikipedia

   en.wikipedia.org/wiki/Self-extracting_archive

   [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. [citation ...

8. ZIP (file format) - Wikipedia

   ZIP is an archive file format that supports lossless data compression.A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common.
