Open Source Windows File Compression Software - Page 7

LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compres

LZPX is a lightweight command-line file compressor. Please note: This program was succeeded by the QUAD.

Implementation of LZW compression/decompression algorithm in Java.

Implementation of the LZW algorithm in C#, adhering to the built-in System.IO.Compression. The algorithm and code is much improved, compared to projects like SharpLZW. The LZW algorithm is for arbitrary lossless data compression and are noticeable for simplicity and low (compared to others) memory consumption. Making it interesting for eg. embedded use. There're many other LZW implementations out there. This one is focused on KISS and C#.

Right-click and unzip, right-click and create zip files, and the software is FREE. For Windows power users who don't want an intrusive ZIP program that gets it's hooks into *everything*, ZCM is the perfect alternative.

This is a complement to http://mssqlcompressed.sourceforge.net. You can specify DBs to backup by name, all, system, online only, or all but system. With a single scheduled task you can backup every database. You can also specify retentions.

MyBackupTcl is a software that allows users (or a system administrators) to create the backup of own files in easy and automatic way. It includes bzip2 compression,GNU PGP,dvd and cd ISO,FTP,e-mail,automatic dumping for mysql,SVN,Trac and much more.

Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte.

The program supports 7z, ZIP, CAB, RAR, ARJ, LZH, CHM, GZIP, BZIP2, Z, TAR, CPIO, RPM and DEB formats.

NoAds FileUnpacker is a free software tool to unpack archives created with TM FilePacker. It does not install any unwanted software on your computer and runs on every Java-supported platform (Windows, Mac, Linux and others).

NoDouble is a duplicate correction tool. It scans your drives for duplicate file. Unlike most tools, it replaces duplicates with hard links. A duplicate file is file with the same content, the same size, but not necessarily the same name or extension. When two duplicates or more are found, at least one of them is replaced with a hard link that points to the same data in the first file. Effectively, a hard link is a file, not a shortcut, and by removing the first file, the second file will still be present with all of its data. However, modifying one of these files leads to the modification of the other.

NuFX or "ShrinkIt" archives are the de-facto standard in the Apple II (and A2 emulator) world. NufxLib is a full-featured library of functions that manipulate NuFX archives (.SHK, .SDK, .BXY). NuLib2 is a command-line utility built on top of NufxLib. THIS PROJECT HAS MOVED TO GITHUB https://github.com/fadden/nulib2

The OS561 operating system based around FORTH/Java. The OS is to run on a VHDL chip OpenHardware design called the Minon, but could become available for other platforms. The unique point of the design is a revolutionary data compression technology.

CRC Hopper is a little tool to fix the crc-failure on some downloaded WinRAR-archives. These archives are not destoid, only defectively. Only 3 clicks fix this little problem.

OpenDark is a free simplification of 'dark'. It's the first open BWT-DC compressor, which has a simple code, high speed and compression ratio. And it's waiting for your ideas! :)

A set of (Perl) scripts that allows you to optimize backups to S3 by packing files/dirs into a minimal set of archives that are likely to remain stable between backups, even if the underlying files change, thus minimizing the number S3 items.

OwlZip est un logiciel de gestion d'archive (zip, rar, cab…) simple, rapide, léger et moderne. Il est compatible avec les fichiers WDZ. OwlZip est personnalisable et ressemblera à votre personnalité avec son fond changeable ainsi que les tuiles et la liste des fichiers. Actuellement en version Alpha, de grande chose vont arriver. (Code source bientôt disponible)

OzVM is a simple, lightweight, secure virtual machine. The current target application of OzVM is OzStream, allowing platform-independent self-decoding data, which abstracts encoded data from client applications.

pgn2pgc converts text Portable Game Notation (PGN) chess files into highly compressed Portable Game Coding (PGC) chess files. This is the only implementation of PGC as described in the PGN standard. Code is also useful for writing chess software.
