Greenleaf ArchiveLib

The Most Cost Effective MultiPlatform Compression Library Available

Until now your development choices for data compression and archiving in C++ or C applications (other languages too!) were severely limited. Professionals, don't be stymied any longer! ArchiveLib 2.0 includes three fast, efficient compression / decompression enginesùone of which provides PKZIP 2.0 compatibilityùand architecture for addition of other compression methods. Control source and destination (file, memory, port, etc.) of all data. Complete control over format of archives.
