BETTERZIP HUFFMAN CODE ARCHIVE

Gzip is not to be confused with the ZIP archive format, which also uses DEFLATE. The final compressed file usually has the extension. Compressed archives are typically created by assembling collections of files into a single tar archive (also called tarball), and then compressing that archive with gzip. ДЄlthough its file format also allows for multiple such streams to be concatenated (gzipped files are simply decompressed concatenated as if they were originally one file), gzip is normally used to compress just single files. an 8-byte footer, containing a CRC-32 checksum and the length of the original uncompressed data, modulo 2 32.a body, containing a DEFLATE-compressed payload.optional extra headers as allowed by the header flags, including the original filename, a comment field, an 'extra' field, and the lower half of a CRC-32 checksum for the header section.a 10-byte header, containing a magic number ( 1f 8b), the compression method ( 08 for DEFLATE), 1-byte of header flags, a 4-byte timestamp, compression flags and the operating system ID.

'gzip' is often also used to refer to the gzip file format, which is: DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of compress and other popular archivers. Gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding.
