• Compress and store data from anywhere, to anywhere in your C/C++, Delphi, and Visual Basic applications!
• Until now, your development choices for data compression and archiving in C++ or C applications (other languages too!) were severely limited. ArchiveLib 2.0 includes three fast, efficient compression / decompression engines - one of which provides PKZIP 2.x 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.
• Now go see why ours is better than PKWare's!

• 100% C++ class library plus "thin" C shell - both C and C++ APIs.
• Includes 3 compress and 3 decompress engines:
• PKZIP 2.0x compatible (Deflate engine)
• Greenleaf engine: lossless, dictionary-based 5-level
• Copy engine as alternative for small files
• Supports Windows 95, Windows NT 3.5x, Win32s, Windows 3.1x, and MS-DOS
• PKZIP 2.0x archive support (even PKWare libraries don't have that!) - insert, extract, delete, list, and more
• Create & manage archive files and/or memory objects to your specifications - the file time/date, attributes, and pathname, comments, compression type, and other information can be included in the archive
• Long filename support for Windows 95, 98, and NT.
• Wildcard expander class with subdirectory recursion is useful for including groups of files, or general-purpose application.
• Progress meter & message classes for Windows and DOS
• Exclusive ObjectGuard™ asserts object memory allocation or pointer errors
• Adjustable compression parameters
• Portable data compression is fast and efficient
• Coded to port easily to any 16- or 32-bit C++ platform
• Release level library versions included; versatile BUILD utility provided to create debug versions of static link libraries and DLLs
• Granular coding allows significant reduction of code linked into applications
• 40 classes, over 250 functions in C and C++ with may example programs to illustrate library usage
• Online Help for Windows; lots of built-in debugging support
• FREE source code; 100% C++ and C
• FREE web-based support
• Other support options available
• No royalties
• Just USD $289.00

Three sets of compression and decompression engines, a general-purpose wildcard expansion and subdirectory recursion engine, the capability to use Windows list boxes seamlessly to input or output a list of files. Handy capabilities like progress monitors are included - a spinner, message, bar graph. Greenleaf's ObjectGuard™ is one of a robust set of debugging tools; it can assert a message if a guarded object has a memory allocation problem or pointer error. Most functions return meaningful error codes

ArchiveLib is written in C++ and also has a thin C shell, so that you can access all functionality from either language. In addition, language independence is assured in DLLs.
