This is a research project to possible improve compression using LZ77, LZSS or bwt, bwt is used on the bzip2 compression library, the v28 from 04/dec/2022 is the first version to almost beat lzma, indeed it is a tweak of lzma, the decoder for v28 will follow in a few days Important: in 13/August/2026 was added the C file lz77_enhanced.c in the section Files, it have an enhanced lz77 implementation, it is better than standard lz77, it compress better, take a look

C code and DLL (with sample project) with library libarchive and GNU tar 1.34 to list, update, delete, extract and create latest GNU tar files uncompressed or compressed with gzip, gzip2, gzip2 multi-thread, bzip2, bzip3, bzip3 multi-thread, lzip, lzop, lzop2, lzop2 multi-thread, lz4, lz5 multi-thread, lzma, brotli, brotli2 multi-thread, Zstandard, xz , the old Unix compression utility 'compress' (.Z) , compress2 multi-thread (.Z2), zip, 7zip and many more formats with full Unicode support when creating and extracting files in windows, compiled with mingw, notice that we have developed a replacement for tar when running in windows with support to file attributes, it is extensible without breaking compatibility with older files, this means that if in the future we add new features to the format it still will be able to extract older VAL files, this is the recommended mode to be used, the extension is .val, support to AES 256, RC4, Serpent, MARS, RC6 and TWOFISH encryption

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

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.
