Open Source File Compression Software - Page 15

A shell script to copy long files into several floppy disks. It tar, compress, uuencoded and split input files. Then copy the generated files in the necessary number of floppy disks. After, all the process can be reversed through the script refloppy

Lrzip is a lossless compression application designed to scale with modern hardware resources using a variety of different back end compression algorithms with the ability to have unlimited size compression windows and optional high grade encryption. The larger the file the better the compression possible and the more powerful the hardware the faster it can compress with a heavily multithreaded design.

LZHW Command Line Lossless Compression Tool is a Windows command line tool used to compress and decompress files from and to any form, csv, excel etc without any dependencies or installations. Using an optimized algorithm (LZHW) developed from Lempel-Ziv, Huffman and LZ-Welch algorithms. The tool can work in parallel and most of its code is written in Cython, so it is pretty fast. It is based on python lzhw library. Full tool documentation can be found at: https://mnoorfawi.github.io/lzhw/6%20Using%20the%20lzhw%20command%20line%20tool/ While the documentation for the python library is at: https://mnoorfawi.github.io/lzhw/

minihuff is a data compression library that enables the creation of a static frequency table to be stored at both ends of a connection. This allows effective compression even for very small pieces of data that maintain similar entropy characteristics.

Apache 2 API module, which serve zipped archive (created by PkWare, WinZip, JAR and other tools) like virtual filesystem and allow browse its content. Usefull for browsing html based documentation (for example generated by javadoc).

The algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode message. Built tree is n-ary one.The algorithm is based on a set of template classes : Cell(SYMBOL, WEIGHT), Node(

niCE - nice insignificant compressing engine, ...oh no, not another data compressor ;-) C-Programm, das mittels Huffmanalgorithmus und Lauflängenalgorithmus komprimiert. Plus: Ausführlicher Guide und Dokumentation die verwendeten Algorithmen und Projek

Windows 32 bit exe and dll packer

A set of bash-functions (probably becomes scripts instead) that perform backups (full and incremental) on blockdevices with encryption and compression using standard tools like tar and mcrypt.

Important: removed xz lib 5.6.1 from all compressed files, now we are using release 5.4.0 because it is stable C code and executable to do an archive of multiples files or folders a la tar, with the advantage of full compatibility with future versions This means that if in the future someone improve the code older files will still be able to be extracted without problems, it looks like an improvement over tar. Its an application to compress and extract files in the .val format, when functional it can be used to replace tar files, the advantage is that it will handle any previous versions without problems, it is almost as fast as tar, for the moment it can generate .val files in gzip, bzip2, bzip3, lz5, brotli2, lzop2, Zstandard, xz and LZMA, but more compression methods will be added like our DLL version of this console application, a lot need to be done yet Documentation at https://parolin.sourceforge.io

PKC (PacKageCommander) is a package manager utility with ncurses and GTK+ interface. You can install/uninstall Debian or RPM packages, or you can configure, build and install a program from a source, and you can make a Debian or an RPM package, and it ca

The development of an open source Prince Of Persia Level editor for PC, a new game engine and complementary tools.

This tool is featured with a very high compression mechanism hence useful in backing up large sized folders over a slow network, Or useful in reducing the backup size to a maximum possible.

English: Pyrotate is Python program for log files rotation. It uses any external archiver such as Winrar, 7-zip or gzip for compress and may rotate files in GNU/Linux logrotate's style. Program works in any OS such as Windows, Linux, Unix, Mac OS, etc, where Python may work. Dependencies: - Python v2.6 or better v2.7 (v2.5 for pyrotate v0.8 or earlier) - an external archiver Russian: Программа для ротации и/или архивации логов (и любых других) файлов, которая использует любой внешний архиватор и может ротировать файлы в стиле Линуксовой программы logrotate в любой ОС, где работает интерпретатор языка Python. Требования: - Python не ниже v2.6, а лучше v2.7 (или v2.5 для pyrotate v0.8 или ранее) - любой внешний архиватор

PZip is a C++ library and application with similar syntax and usage to bzip2 and gzip. The underlying compression algorithm is PPMD and compression performance is significantly better than either gzip or bzip, with similar speed.

Take either manual or scheduled backups using find, egrep, cpio and bzip. Supports weekly full backups, exclusions and compression. See http://bandcamp.tv/quickbackup for mailing list info and downloads

Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.

GUI for the archive zpaq. Графическая оболочка для архиватора zpaq.

Calculates differences of executable files using a randomized algorithm for matching with mismatches.

rubyzip is a ruby module for reading and writing zip files

an implementation of the Inflate decompression algorithm corresponding to deflate compression as used by gzip and compatible with RFC 1951 Written in Z80 assembly language, with memory paging support for the Sam Coupe

squeeze is a python script that compresses a given (set of) file(s) by trying each compression program available on your system and keeping the resulting archive with the smallest size.

Staticcomp is a file archiver. It is a program using library libsc for compressing/decompressing files. Libsc uses compression method based on Burrows-Wheeler transform. For GST stage there are methods MTF, MTF-1, MTF-2, Timestamp, IFC and WFC.

tardiff is a perl utility that enables easy patch creation for two different versions of a build/install tree in tarball format. tardiff uses advanced mechanisms to determine differences (visit homepage for a thorough description).
