This unit is similar to the zlib unit shipped with Delphi, but uses the better compression method present in the program BZip2, which is available at http://www.bzip.org, and is a very popular high-quality data compressor developed by Julian Seward. The advantage of this unit is that it don’t require any extra dll, so you can build stand-alone applications that use it.

If you like to see all the available versions, look at this list:

  • 1.05 - Updated to work with BZIP2 1.0.6. Updated contact information of author. Updated web page address of author.
  • 1.04 - Updated to work with bzip2 1.0.5. Updated contact information of author and bzip2's authors. Fixed a bug detected by Axel Neumann, consisting in that the return value of TBZCompressionStream.Seek was only 32bit with sign, and could cause problems in files bigger than 2GB. Note that this will affect only to Delphi version 6 or higher. Verified that works with almost all versions of 32 bits Delphi and C++ Builder.
  • 1.03 - Added a new demo that show how to compress / decompress bz2 files. Updated web page address of author.
  • 1.02 - Updated to work with bzip2 1.0.2. Updated contact information of author. Added a demo that shows how to work with this unit. Now the home page for the bzip2 program is http://sources.redhat.com/bzip2/
  • 1.01 - Corrections in documentation, the new home page for the bzip2 program is http://sourceware.cygnus.com/bzip2/index.html
