Open Source C Storage Software

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

Darik's Boot and Nuke ("DBAN") is a self-contained boot image that securely wipes hard disk drives (HDDs). DBAN is appropriate for personal use, bulk data destruction, or emergency data destruction for HDDs, but is not recommended for solid-state drives (SSDs), sanitization that requires auditable compliance documentation, or technical support.

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!

Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents. It can be used to view and copy files and folders. It can recursively copy entire folders. It can also be used to view and copy disk and file

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.

pesconvert is a command-line utility for converting Brother PES embroidery files into more accessible formats for viewing or further processing. It parses stitch commands, color changes, and frame boundaries from the binary PES structure and reconstructs the path of the needle across the canvas. The tool emits vector-friendly output so you can inspect or scale designs without losing detail, making it handy for previewing patterns or preparing them for other software. Because the PES format encodes jumps, trims, and thread changes, the converter normalizes these events into a clean sequence of segments. The implementation favors clarity so hobbyists can understand and extend it for their own machine workflows. It’s a practical bridge between proprietary embroidery design files and open tooling.

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

The aim of HxC Floppy Emulator project is to provide software and hardware solutions to replace old floppy disk drives and floppy support with modern solutions (USB, SDCard, network,...)

'di' is a disk information utility, displaying everything (and more) that your 'df' command does. It features the ability to display your disk usage in whatever format you prefer. 'di' also checks the user and group quotas, so that the user sees the space available for their use, not the system wide disk space. 'di' is designed to be portable across many platforms and is great for heterogenous networks.

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

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.

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.

fat_imgen is a utility you can use to create and modify FAT12 floppy images with.

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.

Clean is a program that searches for backup files and such identified by regular expressions in a ~/.cleanrc, and deletes them: possibly interactively with a per-file y/n decision, or in a batch mode. Clean is written in C and targets Unix/POSIX.

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

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

Just an Organizer to organize your whole MP3 and MP4 that are on your machine. You can sort by artist/song/album/etc., read and write Metadata, rip and play CD's

A small program that allows the user to delete files in a secure manner.

Minimalist rework of gzip/gunzip with minimal memory requirement (16KB zip / 2KB unzip) and addons : on-the-fly processing of partial input data (no need to bufferize all data), input from and/or output to memory... Demo/test program also provided

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