7-Zip is a file archiver with high compression ratio. The main features of 7-Zip * High compression ratio in new 7z format with LZMA compression * Supported formats: o ... [More] Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR o Unpacking only: RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO, RPM, DEB and NSIS * For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip * Self-extracting capability for 7z format * Integration with Windows Shell * Powerful File Manager * Powerful command line version * Plugin for FAR Manager * Localizations for 63 languages [Less]

Libarchive is a programming library that can create and read several different streaming archive formats, including most popular tar variants, several cpio formats, and both BSD and GNU ar variants. ... [More] It can also write shar archives and read ISO9660 CDROM images and ZIP archives. The bsdtar program is an implementation of tar(1) that is built on top of libarchive. It started as a test harness, but has grown into a feature-competitive replacement for GNU tar. The bsdcpio program is an implementation of cpio(1) that is built on top of libarchive. [Less]

Compression and decompression in the bzip2 format.

A managed 7-zip library written in C# which provides data (self-)extraction and compression (all 7-zip formats are supported). It wraps 7z.dll or any compatible one and makes use of LZMA SDK.

What is FuseCompress?FuseCompress provides a mountable Linux filesystem which transparently compresses its content. Files stored in this filesystem are compressed on the fly and FUSE allows to ... [More] create a transparent interface between compressed files and user applications. FuseCompress supports different compression methods: LZO, gzip, bzip2, and LZMA. Isn't there a new version?This is the legacy C implementation of FuseCompress (0.9.x tree). It performs slightly less well than the current one implemented in C++ (1.99.x tree), but does not exhibit flaws such as data corruption or files growing larger and larger that make the current code (as of July 17 2008) unusable in a production environment. You can find the new version at Milan Svoboda's website. Because Milan is concentrating on the new version, I am now maintaining the old tree. How well does it work?It works well enough that I have trusted it to handle the vast majority of my private data. I am also using it for my $HOME directory, source trees, and I have (with some really evil hacks) succeeded in installing an openSUSE 11.0 system with FuseCompress as its root filesystem. (That, however, is not something you should currently try at home. At least not on a real system.) LZMA support is experimental. Both the implementation in FuseCompress and the library used by it are not stable yet. Versions 4.999.3 and 4.999.5 of the LZMA library create mutually incompatible streams, for instance. I am still occasionally fixing slight deviations from the expected behavior of a Unix filesystem. These problems are all minor, but may still cause data loss, depending on how robust your applications are. FuseCompress now has experimental support for Mac OS X and MacFUSE. Where to get itPackages for openSUSE Source code can be found in the SVN repository. More informationBuild HOWTO How to use FuseCompress What compression method should I use? [Less]

What this project is:a learning experience practice writing C code learning to create something that is actually useful What has been done:the compression is half done the code builds a balanced tree ... [More] from a file What has not been done:decompression is completely absent for compression, the dictionary builder is not implemented (the last major part before it can be used) The problems with the code:header files contain code that has to be compiled the dictionary builder will have to be aware of the nodes (tree needs to have move left/right functions) I have decided to follow the old Linux versioning scheme. Even version denotes that some major function is done and the odd version indicates that the next major function is being worked on. FUTURE MILESTONES:version 0.2 - Compression is fully done version 0.4 - Decompression is complete version 0.6 - File spec is complete and implemented version 0.8 - command line arguments spec is complete and implemented version 1.0 - There are no problems with 0.8 [Less]

ARX is a archiving file format with advanced features especially designed to meet the requirements of game designers. These features include external data referencing, data synchronization with remote ... [More] data storages, in-memory merging of multiple archives and arbitrary data items structuring.

comprson (union of "compression" and "comparison") takes an input file and applies different compression programs it. The elapsed time of the compression and the compressed size are plotted using ... [More] gnuplot. The purpose is to compare the speed/efficiency of different compression programs. The comprson script has been ported to the following languages: PHP Ruby [Less]
