ComprLib is a library providing a flexible and easy to use interface for encoding and decoding of data, independent of the input and output sources. New codecs able to encode/decode Arithmetic to LZSS have been ported.

A simple software to extract any valid DBPF file, normally they have package extension. This software extracts DBPF files from any The Sims 2, The Sims Stories, The Sims 3 and Spore using command line and has XML support for other softwares.

Compresses music from 1/50th to 1/100th its original size by removing dissonant parts of sound and also optimizes it for lower speaker-stress, dynamic equalization (2-3 times less hearing stress at high volume), non-compression modes and much more.

A Zip/Jar Compressor developed in java for End Users. Un Compresor Zip/Jar desarrollado en java para Usuario Final.

Originally developed as a GUI replacement for the JAR utility included with the Java SDK, this program is expanding to become a cross platform archive utility with the ability to create fully cross platform installation programs.

File management program similar to well known Total Commander for Windows based on multiplatform framework. Consists of two panel display with support of Total Commander plugins.

LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.

A Huffman Coder/Compressor.

Help implement an industrial strength Burrows-Wheeler transform compressor! Initial release covers block-sort, MTF coding, RLE coding, Huffman coding

Language-independent interfaces like DOM, SAX and XSLT are not particularly "Pythonic". Several tools are contained in this "XML2Python Interfaces" project that provide more natural ways of translating between XML and Python objects.

JBackupWithZip is a java program for backing up oftenly some selected folders and files. You select some folders and/or some files by browsing your harddrives and then zip it (in zip format). The selection is saved to redo the zip easily when needed.

Jar Ajar is a JAR-based self-extractor for zip files. Zip up files and package them with descriptive images and text using Jar Ajar's graphical interface. When recipients launch the resulting JAR, Jar Ajar guides users through the unzip process.

An easy-to-use, user-friendly GUI for archived file formats (jar, zip, tar). Explorer-type archive browsing with all the archiving functionality offered through a much easier, quicker & more understandable manner than its command-line counterpart. This project has been replaced by Archive Buddy [http://sourceforge.net/projects/archivebuddy]

Jarsync is a Java implementation of the rsync algorithm, a delta compression algorithm for fast network file transfers.

Java HTML/XML Compressor is a very small, fast and easy to use library that compresses given HTML or XML source by removing extra whitespaces, comments and other unneeded characters without breaking the content structure.

LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compres

Mpyre is a Python front-end to cdparanoia and lame mp3, musepack, ogg vorbis and flac encoders, that includes id3 and apev2 tagging.

MyBackupTcl is a software that allows users (or a system administrators) to create the backup of own files in easy and automatic way. It includes bzip2 compression,GNU PGP,dvd and cd ISO,FTP,e-mail,automatic dumping for mysql,SVN,Trac and much more.

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.

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.

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

A Compression Utility - based on own bit algorithm

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

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.

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 ;)
