Open Source Windows File Compression Software - Page 5

AGfUPX is a nice GUI for UPX with many advantages. Selecting a file using drag & drop, shell integration (adding "Open with AGfUPX" option to the context menu of exe/dll files) and redirecting UPX output to a windows dialog box are only few of them.

Win32 and Win64 DLL to compress files in the standard Gzip format and also the new Gzip2, this format can compress files as large as 9.223.372.036 gigabytes and has also MD5 the integrity check, now also SHA512 too, now with support to multi-threads

Manage rar files in perl.

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.

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) .

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.

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.

CDriveBack backs up partitions for Novice End Users. If the user boots the Live-CD, waits for it to settle, then hits enter, their C: Drive will be backed up. There are also advanced options.

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

CodersBackup is an advanced automatic folder zip backup system. Helps coders (programmers) backup their work based on filters, schedules. Destinations can be local hard disk and/or network and/or FTP. Special actions can be taken during backup.

Coffeearc is a simple, extensible GUI archiver for cmd-line tools. Bundled with CCM and Slug, both ultra-fast and strong compression (including AES encryption) are its core features. Some conventional formats like ZIP, TAR and others are supported.

CAKE is built for Delphi, it's a common interface for 5-6 components related to compression, that means, you can use single code to command all those components, providing open, extract, add, test, convert, find and script loading support.

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.

The Compressor/Decompressor project is a versatile and efficient software solution designed to provide high-performance data compression and decompression capabilities. This project aims to empower users to reduce the size of their data while maintaining its integrity, as well as to efficiently restore compressed data to its original form when needed.

CopyCat is a simple backup program that allows you to schedule regular backups. CopyCat lets you choose to only backup files that have been modified since last time, and compress the files in RAR format if you like.

Crunch is an image compression tool for lossy PNG image file optimization. Using a combination of selective bit depth, color palette reduction and color type, as well as zopfli DEFLATE compression algorithm encoding that employs the pngquant and zopflipng PNG optimization tools, Crunch is effectively able to optimize and compress images with minimal decrease in image quality. While it may produce file size gains larger than those produced by lossless approaches, the impact on image quality is often imperceptible, and optimized file sizes are still significantly lower than the original.

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.

Dreamfiler is a scanned documents and images organizer. It is ideal for offices and workstations that need easy storage and retrieval of important images or scanned documents for daily use. Use tags for easy recollection of data stored via images.

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.

Easy 7-Zip is an easy-to-use version of 7-Zip. Easy 7-Zip was built based on 7-Zip 9.20. It kept all features of 7-Zip and added a few useful features that makes the software more user-friendly.

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

Encrypter is a free folder encrypting and hiding utility software for Windows 32bit platform. Encrypter is powerful but lightweight software written in VB.NET for Windows 7, Vista and XP.
