Open Source Windows File Compression Software - Page 9

Program to experiment with (combinations of) different (lossless) audio encoding methods.

A patent-free audio codec designed especially for voice (unlike Vorbis which targets general audio) signals and providing good narrowband and wideband quality. This project is complementary to the Ogg Vorbis codec.

Java GUI based File Splitter and Joiner. Works on Windows and Linux.

TNT Mocha Backup Platform Independent backup utility written in Java. Uses ZIP files for data storage. Now supports file permission backup for restore by standard utilities in linux such as unzip.

The Bzip2GUI is a graphical interface to the command line bzip2 tool used to compress and uncompress files using the bzip2 format.

The Green Machine is a powerful archive creator, which supports data compression, self-extracting file creation, encryption, file verification via checksums, and much more.

Application for compressing files with different compression algorithms.

UPX with Autoupdate Capability allows the user to pack Firefox and Thunderbird binaries with UPX and use autoupdate without having to backup the original files. This is useful for Firefox and Thunderbird Portable on flash drives with limited capacity.

About UPX Manager: UPX Manager is a Graphical User Interface for the command line based application, UPX Packer. Special thanks to the authors of UPX Packer - Markus Oberhumer, Laszlo Molnar & John Reiser About UPX Packer: UPX (Ultimate Packer for eXecutables) is a portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks for most of the formats supported, because of in-place decompression. Visit UPX Packer homepage - http://upx.sourceforge.net

Batch extraction of RAR compressed archives

WRoX-SFV - is a Windows GUI .sfv checksum application, with the checksums it creates you can check for edited, changed, currupted files. Features: recursive .sfv checking, .sfv file association, windows context menu integration, automatic unrar/unzip

Waveform Archiver

Console utility for performing 7zip with unbuffered I/O Currently all archive, compression software and libraries are using buffered I/O which brings your machine to zero memory for large files. This console application uses the SevenZipSharp library with unbuffered I/O which gives all the options of 7zip without the memory problem. The supported compression algorithms are: Deflate, Deflate64, BZip2, Lzma, Lzma2, and Ppmd The supported archive formats are: SevenZip, Zip, GZip, BZip2, Tar, and XZ

WinPass has been canceled due to obsolecence with the release of Windows XP

WinRAR is a powerful file archiver and compression tool that supports multiple file formats, including RAR and ZIP. It is widely used for compressing large files into smaller, more manageable sizes and decompressing files into their original format. WinRAR offers advanced features for both personal and professional use, such as file encryption, password protection, and splitting large files into smaller parts for easier storage or transfer. Its intuitive interface makes it easy for users to compress, encrypt, and share files quickly and efficiently.

Lossless compression program with various algorithms included. Intended for large XML files, but can compress any files. Best results with block compression (BWT+MTF+RLE) on large block over alphabet of words.

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.

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.

A simple library for unzipping Zip Files using C#. This does not presently handle zipping, if you are interested in contributing, contact me. I made this because it was hard to find a completely free unzipping library for C#.

Microsoft .NET Stream-derived objects that wrap ZLib inflate and deflate as well as Base-64 functions (C++ Mixed Mode implementation)

ZipBackup is a free Windows tool for maintaining backups of your files and folders. ZipBackup focuses on providing simple file backup in an open, common file format instead of a proprietary format that locks you into a particular backup software. Full and incremental backups are automatically provided. ZipBackup also supports 256-bit Advanced Encryption Standard (AES) security for your zip files - the same security used by the NSA for classified information. With both compression and encryption, this combination makes ZipBackup an ideal tool for storing backups offsite on systems such as DropBox or Google Drive. ZipBackup also provides a restoration panel where you can view and retrieve your previous backups. The tool lets you view or extract your files and folders as they were when the backup was made, regardless of the complex combination of full and incremental backups holding your data behind the scenes.

ATL COM objects for manipulating .zip files. Currently it is only posible to create new files, but I hope to add extration, and editing soon.

ZipDB is a program that allows databases to be made easily and efficiently using compressed zip files. An easy-to-use gui is the key feature allowing quick access to all files in the archive, and since the archives are .zip they can always be opened on

A windows compression app zips and unzips multiple directories. Unzip many zip files at the same time and make subdirectories. App for partial backups. Zip multiple directories to separate zip files with recursion. UnZipDir is the newest version.
