Open Source Mac File Compression Software - Page 5

Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte.

NoAds FileUnpacker is a free software tool to unpack archives created with TM FilePacker. It does not install any unwanted software on your computer and runs on every Java-supported platform (Windows, Mac, Linux and others).

The OS561 operating system based around FORTH/Java. The OS is to run on a VHDL chip OpenHardware design called the Minon, but could become available for other platforms. The unique point of the design is a revolutionary data compression technology.

A set of (Perl) scripts that allows you to optimize backups to S3 by packing files/dirs into a minimal set of archives that are likely to remain stable between backups, even if the underlying files change, thus minimizing the number S3 items.

This project provides a graphical user interface for the PAQ compression program. It is written in Java.

pgn2pgc converts text Portable Game Notation (PGN) chess files into highly compressed Portable Game Coding (PGC) chess files. This is the only implementation of PGC as described in the PGN standard. Code is also useful for writing chess software.

PHP Unarchiver is Un-Archiver tool that works with Tarballs, Zips and Rars. Unarchiver is a browser-based archive management tool for users who do not have direct access to their servers.

INACTIVE PJZip is an open source zip-tool based on PersonalJava standard 1.2 by SUN. (ZIP-tool for Pocket PC)

PAT is a complete web application that allow to manage files (basic and advanced functions like compression in gz), ftp, and database all in one. Designed to reproduce a Graphical User Interface (GUI) with drop-down and context menu for easy use

PhpZip is a PHP application which manage compressed archives. PhpZip can archive and extract files and file systems (files + folders). PhpZip support several archive formats (proprietary, GNU TAR, Compressed, ...).

A Compression Utility - based on own bit algorithm

RAReXtract is a Front-End for the UnRAR command line utility for Mac OS X 10.5 (Leopard). Its purpose is the rapid and convenient extraction of RAR archives with a double click.

The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. During the desing phase, some other features were added, like encryption and error correction.

Simple light-weight file compression and decompression utilities. Written in C and portable to all platforms. Simple compress and decompress subroutines can be linked and called within applications to compact or unpack data on the fly or stand-alone.

SEG-Y files need special compression because they don't compress well using gzip and the like. The code is cross-platform C++ using nothing else than standard system libraries. This is a spin-off from the OpendTect project (http://opendtect.org).

SMSCompress is a project of investigation, development and implementation of different SMS compression techniques. Using these techniques, SMS of more than 160 characters can be sent at only one SMS, saving money to the user ;)

A plattform independent encryption-tool with a simple user interface (swing/java). It uses 'Password Based Encryption' (PBE) to encrypt and/or decrpyt files on the filesystem. Encryted files will also be compressed using the zip-format.

A search, filter, and "action" utility targeted at power users and developers. Features a graphical and command-line interfaces. Initial version searches for/filters files then does whatever you specify (copy, delete, move…).

A database system, another, older database system, a compression library, something to do with menus and XML, and whatever I happen to be working on at the time.

This project is built for learning purposes so it's implementation is kept simple and easy to read. It has two functions to either encode or decode a file with the expectation that you will modify it to suite your needs best.

Simplify is aimed to raise images compressibility by using a reversible blurring algorithm.

Slim is a data compression system for scientific data sets, a binary and a library with C linkage. Slim works with integer data from one or more channels in a file, which it can compress more effectively and more rapidly than general tools like gzip.

Softcabq

Program to experiment with (combinations of) different (lossless) audio encoding methods.

Java GUI based File Splitter and Joiner. Works on Windows and Linux.
