ABC (Advanced Blocksorting Compressor) is a free data compression program based on the Burrows-Wheeler transformation. The source code is free for academic, research and educational use as depicted in the Abel Public License (APL).
The program is developed in OBJECT PASCAL (DELPHI), since the author prefers the structure of PASCAL over C/C++. The program is a command line program just like GZIP. It is not an archiver program but compresses each file file separatly. Itīs intention is to compress files and get average compression rates and compression/decompression times for a single file or a corpus.
The sorting buffer size is 5 MB.
Currently ABC supports only 32 bit WINDOWS systems: WINDOWS 95/98/NT/2000/XP
