Open Source C++ File Compression Software - Page 2

This project has moved to GitHub https://github.com/Zipios/Zipios Zipios is a C++ library for reading and writing Zip archive files. Access to the data of individual entries is provided through standard C++ iostreams. A simple read-only virtual file system that mounts regular directories and zip files is also provided.

BALZ is a command-line file compressor with a high compression ratio and fast decompression.

Tiny File is a small tool for compress and decompress your file. Is a simple Gui for 7zip,but is very cute !!!! Compresses files and folders in ZIP, 7ZIP, Gzip or TAR format!!! I am looking for developers for the project.......

Waveform Archiver

This project has been moved to https://github.com/inikep/XWRT XWRT (XML-WRT) is a high-performance XML compressor (it also works with textual files). It transforms XML to more compressible form and uses zlib (default), LZMA, PPMd, or lpaq6 as back-end compressor. It is similar to XMill, but has many improvements.

DM-commander is a fast and powerfull two-pane file and archive manager for Windows.

qiewer extractor is a Shell Namespace Extension. This allows browsing various archive formats with the Windows Explorer. The supported formats are: .zip / .rar / .7z / .001 / .tar / .gz / .bz2 / .lzma / .xz / .lz While browsing it's possible to copy from the archive by clipboard or drag&drop. Or simply use the "Extract..." from the context menu, which extracts all contents into one folder.

wxWidgets based cross platform 7-Zip File Manager GUI for Windows, Linux and Mac.

.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.

AbZip is a Qt based C++ class for creating Zip archives. It's not a wrapper for other Zip/Unzip code but accesses the archives directly via QIODevice

libarxx is a C++ archiver with advanced features, like data synchronization and merging of multiple archives. It provides an object-oriented view on a directory tree of data items and allows versioning, compressing and structuring in multiple ways.

Atol is a classical dual panel file manager aiming to be portable to both Linux and Windows OS (using C++ and GTK+ toolkit)

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.

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.

This is an academic project. A library and a sample program will be developed, that will implement the Burrows-Wheeler compression algorithm, using C++ and templates. This is the same algorithm for BZip.

Multi-threaded HDF5 filter using ESA CCSDS-123 implementation

C++ Windows Rar let the plastaion emulator can play iso files and the iso files compressed by rar zip also with an radom access rar files library

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

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.

Lepton image compression, saving 22% losslessly from images at 15MB/s. Lepton achieves a 22% savings reduction for existing JPEG images, by predicting coefficients in JPEG blocks and feeding those predictions as context into an arithmetic coder. Lepton preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5 megabytes per second and decodes them back to the original bits at 15 megabytes per second, securely, deterministically, and in under 24 megabytes of memory. We have used Lepton to encode 16 billion images saved to Dropbox, and are rapidly recoding our older images. Lepton has already saved Dropbox multiple petabytes of space. At Dropbox, the security and durability of your data are our highest priorities. As an added security layer, Lepton runs within seccomp to disable all system calls except read and write of already-open file descriptors. Lepton has gone through a rigorous automated testing process.

DyConnect is a cross-platform networking library for C++. Features include: synchronized variables for rapid development of networked games, multi-threaded TCP/IP, low-level UDP sockets, support for IPv4 and IPv6, and data compression.

Yet another Zip library in C++, with high abstraction level and ease of use.

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.

Exalt (An Experimantal XML Archiving Library/Toolkit) is a library for efficient compression of XML documents. Exalt is an academic project.
