Army Builder file format compression

According to the Army Builder developers the compression used in .ab files is a customised, commercial version of LZW (the compression used by PKZip). Based on error messages within the EXE files it appears ArmyBuilder uses Greenleaf Software's ArchiveLib. Since the files are not directly PKZip-compatible (as claimed in the Army Builder 2 documentation), the compression method used must be the proprietary GLCompressor.

One of our developers, darpified, has undertaken investigations to reverse-engineer the .ab file format compression. Details of this compression will appear here for use by other projects and individuals as and when they are discovered.
