The LZMA compression algorithm as used by 7-Zip. .lzo application/x-lzop lzop: Unix-like An implementation of the LZO data compression algorithm. .rz rzip: Unix-like A compression program designed to do particularly well on very large files containing long distance redundancy. .sfark sfArk: Windows compress/decompress- Linux and macOS ...
The .ZIP file format was designed by Phil Katz of PKWARE and Gary Conway of Infinity Design Concepts. The format was created after Systems Enhancement Associates (SEA) filed a lawsuit against PKWARE claiming that the latter's archiving products, named PKARC, were derivatives of SEA's ARC archiving system.

7-Zip includes read support for .msi, cpio and xar, plus Apple's dmg/HFS disk images and the deb/.rpm package distribution formats; beta versions (9.07 onwards) have full support for the LZMA2-compressed .xz format.
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.
bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.It only compresses single files and is not a file archiver.It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting.

For example, it may use Bzip2 to compress .txt files, while using Deflate for files with a .exe extention. For .com or .sys files, ALZip uses the ALZ algorithm. The ALZ algorithm is slower but has a high compression ratio. It has a faster compression rate than the Deflate algorithm used in the ZIP format, and is comparable to the LZMA algorithm ...
If the archive is compressed, libarchive also detects and handles compression formats before evaluating the archive. [6] libarchive is designed to minimize the copying of data internally for optimal performance. [7] Supported archive formats: [8] 7z – read and write; ar – read and write; cab – read only; cpio – read and write; ISO9660 ...
