The LZ stage is followed by entropy coding using a Markov chain-based range coder and binary trees. The following compression methods are currently defined: The format's open architecture allows additional future compression methods to be added to the standard. to re-assemble an archive from a set of multi-part component files).
Large file support (up to approximately 16 exbibytes, or 2 64 bytes).High compression ratios (depending on the compression method used).Open, modular architecture that allows any compression, conversion, or encryption method to be stacked.The 7z format provides the following main features:
