The URARFileLib is a small static library that allows you to read files from RAR archives created with RAR and WinRAR. Listing, decompression, and decryption with full RAR 2.0 compatibility is done directly in your application, so there is no need for a DLL or any other external file. It is based on the free unRAR source code by Eugene Roshal, and designed for easy but powerful usage in demos and intros. It is also useful if you want to port your programs since the it is written in pure ANSI C (some parts are optimized in assembly) and supports multiple operating systems.
The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. Its major features include fast random access to compressed data, freedom from patents, single-pass coding/decoding using a bounded amount of intermediate storage, the ability to choose from one of many algorithms for compression, encryption, or error correction, and comprehensive support for Unix file metadata, Macintosh file metadata, and arbitrary file metadata.
CFL (Compressed File Library) is meant for the save-files used by games, and other sorts of data files. Its features include pluggable class factories, easy CFL file creation at runtime, and the ability to have multiple separate CFL objects in memory at the same time. The package also includes a CFL testing tool to make it easier to port the library and to create additional plug-in compressors, preprocessors, and ciphers. It also includes a makecfl utility, which makes it easy to create ini files.
The GNOME Structured File Library is a utility library for reading and writing structured file formats. Support for MS OLE2 streams is complete, as is zip import. There is also support for document metadata and some initial work on decompressing VBA streams in OLE files for future conversion to other languages. This library replaces libole2 and is used in gnumeric, mrproject, abiword, libwv2, koffice. It is also part of the AAF format.
DJWrap is an effort to create an open format for combining several MPEG audio streams into one, without losing information about the original files and without disturbing the stream with erroneous or misplaced data. To this is added MD5 checksumming of each individual substream as well as an extendable data format which will, to the furthest extent, provide both backward and forward compatibility. It also supports both DJWrap and AlbumWrap files, and therefore replaces ALBWtool, which has been discontinued.
