Open Source C# File Compression Software

pngcrush and other tools for manipulating PNG (Portable Network Graphics) and MNG (Multiple-image Network Graphics) files.

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#.

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.

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 very simple but effective FastDL Server for Counter Strike that allows your game server clients to download your server content from a HTTP service.

.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.

Track all your files, locally, on CD-ROMs, and on removables.

Using the LZMA compression library ported to c#, I intend to make a multi threaded archival system, that will compress files (slice them a set number of times) and use up to 4 threads for compressing those files.

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.

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

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.

PowerPAQ will be GUI application that will use strenght of GPL-licensed PAQ compression algorithm. This algorithm is slow but extremely powerful. First, windows version will be out. Next step is Linux GUI version. ==Project is coming back to developement with new ideas!===

R-Decompressor is a recursive RAR and ZIP decompression utility, you can decompress accross directories and in a recursive way with optional deletion of processed files. Multipart RAR files are supported.

SharpArchiver is a simple to use file archiver.Fully supporting Zip,7Zip,Lha and Sqx archives.Open and Extract support for 47 different archive extensions(Zip,7z,Tar,Gzip,Bzip2,Arc,Arj,Asd,Ace,Cab,Rar etc.).

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

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

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#.

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.

About the program: Banal Zip archiver Created by a 12 year old man :) My YouTube channel: MrOlegTitov --------------------------------------------------- This program was created in 1 hour 10 minutes If you want to support me: YandexMoney: 4100110731481746 WebMoney: 519227791003 --------------------------------------------------- This archiver is completely free! But again you can support me))) ( But I'm not suggesting anything..... )

Simple file compressing program using Huffman coding. Written in C#.

A windows backup application. Integrated web server allows remote control; iPhone-style web-application available; Enhanced security options. Virtual drive allow users to browse their files easily.

A very simple dictionary based text compressor. Created to shorten single line UTF8 strings; it tries to compress them quickly with a simple interface that can be used as a drop in replacement for Encoding.UTF8.GetBytes(value) and Encoding.UTF8.GetString(packed). The public Litc API are in fact: byte[] packed = Litc.GetBytes(value); string unpacked = Litc.GetString(packed);

Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.
