Open Source C File Compression Software - Page 4

DEPRECATED - This is now hosted at https://github.com/Yeraze/ytnef ytnef is a program to work with procmail to decode TNEF streams (winmail.dat attachments) like those created with Outlook. Unlike other similar programs, it can also create vCalendar/vCard entries from meeting requests, address cards, and task entries.

Zip file alternative protection mechanism for passing zip files across public networks or to bypass scanning mechanisms of the contents.

Experimental command line compression utility to experiment with various compression algorithms.

Simple, fast implementation of LZW (Lempel–Ziv–Welch) data compression algorithm in C. - Console encoder/decoder tools - OS independent - Could be used in embedded projects - Works with raw code-stream LZW features: - Hardcoded dictionary size - Variable code size - Code search is performed by hash table and embedded in dictionary linked lists (encoder) - No dynamic memory allocation

czip is a unix based utility written for the cell broadband engine. It allows its users to compress files in gzip format. It uses Jean-loup Gailly's deflate algorithm and is based in part on pigz, Mark Adlers parallel version of zlib.

Indexed Tar file creation and extraction program.

Linux executable compressor using UCL. The small decompressing stub is written in assembler.

fpsc is a Fast Parallel Stream Compressor. It can use multiple CPUs to compress (gzip or bzip2) a data stream. (from stdin to stdout) It is built to achieve maximum throughput, everything else (especially memory usage) can be sacrified.

Fqzcomp is a basic fastq compressor, designed primarily for high performance. Despite that it is comparable to bzip2 for compression levels.

garchiver is an archiver for Gnome. It has a tree interface that lets you navigate through your archives very easily, as well as the classic WinZip interface. It also has full drag and drop support.

Gnochive is a Gnome front end for all archivers under linux.

gqviewarc is an LD_PRELOAD module that makes GQview image viewer treat archives (ZIP, RAR and maybe more) as directories. It may also be applicable in other domains where transparent stream read access to archived files is needed.

gzx is a C library and a command line tool for fully GZIP-compliant file compression with fast random access read support. gzx includes a FUSE (filesystem in userspace) client that allows to access the compressed files with arbitrary applications.

gzzzzzz enlarges a given file 6 times and writes it as a gzip file. It therefor can be "decompressed" (which makes it 6 times smaller) with the standard gzip. This shows that gzip (and deflate and any compression tool that uses one of them) but also, as I expect, any other compression format can be used to augment data significantly.

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

A resource-conscientious, flexible, modular, platform-independent, scalable and robust server based on ircd-ratbox.

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.

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.

Lrzip is a lossless compression application designed to scale with modern hardware resources using a variety of different back end compression algorithms with the ability to have unlimited size compression windows and optional high grade encryption. The larger the file the better the compression possible and the more powerful the hardware the faster it can compress with a heavily multithreaded design.

makeutil is a set of portable public domain programs designed to support C/C++ projects. It provides tools for build operations outside of the normal compile/link pipeline. It is designed to be unobtrusively included directly in your own project.

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).

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

Important: removed xz lib 5.6.1 from all compressed files, now we are using release 5.4.0 because it is stable C code and executable to do an archive of multiples files or folders a la tar, with the advantage of full compatibility with future versions This means that if in the future someone improve the code older files will still be able to be extracted without problems, it looks like an improvement over tar. Its an application to compress and extract files in the .val format, when functional it can be used to replace tar files, the advantage is that it will handle any previous versions without problems, it is almost as fast as tar, for the moment it can generate .val files in gzip, bzip2, bzip3, lz5, brotli2, lzop2, Zstandard, xz and LZMA, but more compression methods will be added like our DLL version of this console application, a lot need to be done yet Documentation at https://parolin.sourceforge.io
