Open Source ChromeOS File Compression Software - Page 2

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.

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

A simple C++ library to code/decode data.

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.

LZPX is a lightweight command-line file compressor. Please note: This program was succeeded by the QUAD.

.NET wrapper for 7Zip, based on 7-Zip-JBinding, produced with IKVM. Extracts (password protected, multi-part) 7z Zip Rar Tar Split Lzma Iso HFS GZip Cpio BZip2 Z Arj Chm Lhz Cab Nsis Deb Rpm Udf archives. Archive creation/more formats coming soon.

Depack routines for old Atari ST packing programs like Ice, Atomic etc.

BCM is a high-performance file compressor that utilizes advanced context modeling techniques to achieve a very high compression ratio. All in all, it's like a big brother of the BZIP2.

BeoZip is a Java application that backs up data into ZIP files while also providing additional archiving utilities. This program uses the Java APIs for reading and writing ZIP files.

BiGZiP is a graphically rich, Java based compression tool. It is developed around a user interface that is easy and intuitive to navigate. It fully supports zip compression and allows for the development of new compression schemes via it’s APIs

Binary XML is java library. Major feature of library is document encoder/decoder which helps to store DOM model in binary format and retrive DOM model back. Encoded file size extremely small (in about 10 times relatively to original) .

New compression method based on bit repacking.

Blackfisk is an application that does backups. It differs from other backup-software in the way how to use it. The software can handle huge and complex backup tasks.

A shell script which determines by brute force the best compression format (bzip2, gzip, Z, zip, etc.) and which compression level to use in order to archive a file the smallest possible.

CADI is an implementation of the JPIP standard (JPEG2000 Interactive Protocol - Part 9). CADI includes a JPIP server, a JPIP proxy, and a JPIP Client. CADI is designed and programmed with the aim to provide a flexible framework to test and develop ne

Numerically estimate an efficiency of code construction algorithms. Randomly generate n binary words of length m with minimum Hamming distance d and create a prefix code (= retrieval tree) from them. Based on PhD work.

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.

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.
