Open Source C Archiving Software for ChromeOS

Info-ZIP portable compression/archiver utilities (Zip, UnZip, WiZ, etc.)

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

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

Remote Subversion repository dump

Providing a tool to apply the data-recovery capability concepts of RAID-like systems to the posting & recovery of multi-part archives on Usenet.

ARC is used to create and maintain file archives. An archive is a group of files collected together into one file in such a way that the individual files may be recovered intact. This repo is obsolete. Use github.com/hyc/arc instead.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

Moved to GitHub.com/gdraheim/zziplib/ The ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by Zlib. It provides functions that transparently access files being either real files or zipped files, both with the same filepath

The littleutils include duplicate file finders (repeats, repeats.pl, repeats.py), image optimizers (opt-jpg, opt-png, opt-gif, recomp-jpg), file rename tools (lowercase, uppercase, pren), archive recompressors (to-gzip, to-bzip2, to-bzip3, to-7zip, to-lzma, to-lzip, to-xz), a tempfile utility (tempname), file property tools (filedate, filemode, filenode, fileown, filesize, and lrealpath), and others. See the README file for more details.

Free virtual appliance to backup and replicate Linux servers and ©VMWare ©ESXi virtual machines from version 5.1 to 8.0. https://33hops.com/xsibackup-app-detailed-installation-instructions.html ©XSIBackup-App connects to multiple Linux or ©ESXi servers and backs VMs & files up to, local disk, NFS, iSCSI, Samba, etc... or to any Linux or ©ESXi server over IP, it just needs the SSH port open. This appliance is based in CentOS 7 and has root access. You can install any available software, including drivers for Amazon S3, Azure, Google Cloud, etc... We have improved speed with regards to the hypervisor service versions, mainly due to more flexible buffering. It follows the same principles and command line arguments as ©XSIBackup-DC. This new approach has many advantages over the software running directly in the Hypervisor OS, as it can backup an unlimited number of servers from a centralized console and you don't need to install anything in the Hypervisor OS

Alo is the easy way to write XML data from C programs.

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

New compression method based on bit repacking.

Alternate language bindings for the libdar library written by Dennis Corbin. The original application DAR is a command line backup tool that uses libdar, a library implemented in C++.

liblzg is a minimal implementation of an LZ77 class compression library. The main characteristic of the library is that the decoding routine is very simple, fast and requires no memory.

APR based virtual file system library and modules for read/write access to gzip, bzip, tar, cpio, iso and zip archives.

Depack routines for old Atari ST packing programs like Ice, Atomic etc.

BaverBurner is a GUI frontend for cdrecord, cdrdao and dvdrecord. It will be able to create Data CDs, Audio CDs from your MP3/OGG collection, Data DVD's and Video DVD's once completed. It requires a valid C compiler and GTK+-2 libraries, as well as cdto

CAIRN is a modular copy and restore program for the imaging of a computer. It copies every file on a computer and figures out how to recreate it from scratch. It is primarily network oriented but is also flexible enough to boot from any possible method.

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.

fbreak is a console application that allows you to break a large file into multiple smaller files (ie, for distribution on floppy disks).

A library with the intent to provide a single interface to files and data in various locations, like inside archives and across the internet.

LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.
