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

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

Compression/decompression library, capable of operating on a stream and intended to be used on systems restricted in code and stack size.

Using the LZMA compression library ported to c#, I intend to make a multi threaded archival system, that will compress files (slice them a set number of times) and use up to 4 threads for compressing those files.

File2PNG was designed to pack all files in the PNG image format in order to facilitate secure file transfer where it is not supported to retrieve all types of files, such as images or hosting social networks.

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.

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.

Implementation of the algorithm of the paper: "Fractal image compression based on Delaunay triangulation and vector quantization" It is a Fractal compression algorithm, based on relationships between regions of the image (in this case triangles), rather than in explicitly the pixel values themselves.

I wanted to take regular differential backups of my files, zip and password protect them, then upload them to some nice free online storage. I want it to run seamlessly, no messing with a GUI every week.

GD RCS is a revision contol system which supports repository on removable media. It combines the abilities of PRCS, archiving tools like Zip and backup utilities.

GNet Server - Network compression client/server software. Compresses data over slow networks to save on the cost of bandwidth. Server is developed for Unix and Windows platforms, The client will run on Windows based PCs.

Grey Compressor+FTP compresses and uploads a single.7z (7-Zip) file to an ftp server. An output .bat file and password .txt file are produced. Send the .bat file and .txt file to the recipient. The recipient then double-clicks the .bat file, and the .7z file is downloaded to the recipient's computer. Pros: * The bat file produced after the file/folder is compressed is the same size each time (easy to send to recipient). * No need to upload compressed file to ftp and send recipient shared url. * Automatic encryption. Cons: * Grey Compressor+FTP may not download .7z file when connected to certain domain networks. * The sender and recipient must have an internet connection. Tips & Tricks: * Rename .bat to .batx if your email service blocks sending your .bat file via email. Recipient then must change the file extension back to .bat. *Grey Compressor+FTP currently has 375 GB of shared server space. This will increase as downloads increase.

A Huffman Coder/Compressor.

THIS PROJECT HAS BEEN MOVED TO GITHUB: http://github.com/drichardson/huffman

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

Infinity is a fractal compressor (based on high mathematical theories) done by a university assigment. It will be based on neural networks (an innovative approach) and coded in C++

Expandable multi-player online spacegame with influences of MUD & IRC.

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.

Iterative Compression Algorithm: trying to prove Shannon was wrong.

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.

JOpenZip aims to be the leading Open Source archive utility program for most platforms. This will be achieved through the use of the Java platform, and support is planned for most archive file formats like Zip, GZip, BZ2, Tar and TGZ.

A simple pdf compression tool written in Java Using Itext PDF library for java

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]

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.

Jrar is a fast and effective frontend to the RAR and UNRAR programs. Programmed completely in Java it will be able to work on any computer that has a port of the Java2 runtime and the (UN)RAR programs.
