Open Source Windows File Compression Software - Page 11

Simple file compressing program using Huffman coding. Written in C#.

A windows backup application. Integrated web server allows remote control; iPhone-style web-application available; Enhanced security options. Virtual drive allow users to browse their files easily.

imigrate allows you to upgrade both schema and data for any size of Informix db(e.g. terabyte)

This app intents to be an easy way to make backups of large amount of files into medias such as CDs or DVDs. Also it compress groups of files to fit in the size of dest. media. To avoid integrity problems during decompression, no files are divided.

jShrinker is written in Java and can de/compress 7zip*, zip, bzip2, tar, lzma, rar, and gzip formats. It aims to be cross-platform and to provide an easy-to-use interface. It will include these features: batch decompression. *Decompress only

The jbig2dec project is no longer hosted here. Please see: https://www.ghostscript.com JBIG2 is a compression format for lossless and lossy encoding of scanned monochrome documents at moderately high resolution. It is very efficient in that domain, claiming 100:1 compression. jbig2dec is a decoder-only implementation of the format.

jiz--an open source, multi-platform java swing based archiver for java based archive file formats and zip files.

Java JNI library to extract ACE archives using UnACE shared library

jzip is a zipping/archiving program, written in Java. It let's user use gui to create zip archives and Jar executables archives. The very fact that it is using Java allows use on many platforms.

larra provides some simple interfaces for archive access. The main feature is that it uses the same interface for directories and archives, which allows archive-in-archive access (like .tar.gz). For file access a seekable stream interface is used.

A simple backup utility for MS Windows used through the Send to menu.

liblzg is a minimal implementation of an LZ77 class compression library. The main characteristic of the library is that the decoding routine is very simple, fast and requires no memory.

A very simple dictionary based text compressor. Created to shorten single line UTF8 strings; it tries to compress them quickly with a simple interface that can be used as a drop in replacement for Encoding.UTF8.GetBytes(value) and Encoding.UTF8.GetString(packed). The public Litc API are in fact: byte[] packed = Litc.GetBytes(value); string unpacked = Litc.GetString(packed);

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

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.

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