The compression algorithm is a modified LZSS, with an adaptive Huffman coding. .genozip application/ vnd.genozip: genozip: Linux, macOS, Windows Genozip, a compressor for genomic file formats such as FASTQ, BAM, VCF and others. [4].gz application/ gzip [5] gzip: Unix-like GNU Zip, the primary compression format used by Unix-like systems.
Zstandard was designed to give a compression ratio comparable to that of the DEFLATE algorithm (developed in 1991 and used in the original ZIP and gzip programs), but faster, especially for decompression. It is tunable with compression levels ranging from negative 7 (fastest) [6] to 22 (slowest in compression speed, but best compression ratio).
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.

libzip supports reading and writing zip archives. In particular, it allows extracting single or multiple files and querying their attributes (including extra fields and comments). For writing, it allows replacing files or adding new ones; the data can come from buffers, files, or even other zip archives (without recompression).
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.
A bug in the compression process can cause run-away generation of useless log files both in that folder and in C:\Windows\Temp, which can consume disk storage until completely filling the hard drive. [15] [16] Deletion of the files without following a specific procedure [16] can cause the deleted files to be regenerated at an increased pace.
This leads to Deflate64 having a longer compression time, and potentially a slightly higher compression ratio, than Deflate. [7] Several free and/or open source projects support Deflate64, such as 7-Zip , [ 8 ] while others, such as zlib , do not, as a result of the proprietary nature of the procedure [ 9 ] and the very modest performance ...
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.
