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 engines-one of which provides PKZIP 2.0 compatibility-and architecture for addition of other compression methods. Control source and destination (file, memory, port, etc.) of all data. Complete control over format of archives.
