lzma compression file format

Anonymous Coward writes | more than 7 years ago

Programming 1

An anonymous reader writes "The guys at The Tukaani Project are developing a new compression program (similar to older gzip/bzip2) and a library (with a zlib-like API) based on the LZMA compression alghoritm of Igor Pavlov. Some features of the LZMA alghoritm are:

  • Average compression ratio of LZMA is about 30% better than that of gzip, and 15% better than that of bzip2.
  • Decompression speed is only little slower than that of gzip, being two to five times faster than bzip2.
  • In fast mode, compresses faster than bzip2 with a comparable compression ratio.
  • Very similar command line interface than what gzip and bzip2 have.
  • Free software licensed under the GNU GPL (actually most parts are under the GNU LGPL).
The first draft of the new .lzma file format specification is out and the developers are requesting feedback: http://tukaani.org/lzma/header-format-12.txt
There are also the experimental LZMA utils available for download at: http://tukaani.org/lzma/"

7-zip (1)

How is it different from 7-zip? 7-zip is GPLed, and has a SDK:
