Release date (Fri Sep 18 17:48:46 2009)

bzip2 dll 

Win32 dll to compress files in the Bzip2 and Bzip3 format

What is new  (Tue Sep 01 14:17:55 2009) Minor modifications, requires rspbzip2.dll in the same path of the ocx

What is new   (08/05/2008 13:12) : Windows Vista compliant , fixed a few small bugs 

What is new   (Thu Nov 15 11:38:26 2007) : Added the new Bzip3 format, the new Bzip3 format can compress files up to 2^63 or 9.223.372.036 gigabytes and has also MD5 as the integrity check , also stores attributes and file time , the Bzip3 mode can be used with the functions CompressBzip3 and DecompressBzip3 , use the old Bzip2 mode only if you really need Bzip2 compatibility , the old Bzip2 mode has a file size limit of 2 GB , notice also that a Bzip3 file is not a Bzip2 and vice-versa , both formats has different headers , the Bzip2 header is "BZh" and the Bzip3 header is "RSPB", minor bugs fixed 

What is new   (01/Feb/2004 17:44) Improvement in the speed execution up to 20 percent faster than older versions , this improvement is the result of new Intel and AMD specific optimizations added to the bzip2 engine, added new CPU detection code , modified several internal functions for reliability , added more error handlings , fixed minor bugs , the upgrade is highly recommended

What is new   (14/12/2003) Fixed bug in the ResumeCompress , PauseCompress and CancelCompress functions that will show an aboutbox when the first function called are any of these 3 functions , fixed a bug in the selection
of the compression level that will cause the control to use only the level 9 , minor bugs fixed


- Ability to compress and decompress in the Bzip2 or Bzip3 format

- When Bzip3 mode is used the file size limit is 2^63 bytes or 9.223.372.036 gigabytes and save attributes and file time

- The control can pause , resume and cancel the compression and decompression execution

- The compression code is loaded dinamically in the
process of the software using the control

- The control can provide progress information about the compression and decompression functions

- The code execution is optimized for speed , but the original Bzip2 compression format is really slow to execute , future versions may have a faster implementation of the Bzip2 compression format


- Just extract the files to an empty path and open the project in C#

Operating System Compliance

Windows 98 , Windows Millenium , Windows NT 4.0(sp6a) , Windows 2000 , Windows XP , Windows Vista
