Description

With the introduction of version 5, be prepared to experience the ultimate in reliability, speed, and ease of use. New features abound, including support for the newest zip format (4.50), huge zip files of unlimited size, enhanced multivolume zipping, Enhanced Deflate (PKWare calls it "Deflate64 TM"), a large, newly updated library of sample source code, diagnostic utilities, and much more. It's also the value leader, with two easy-to-swallow product configurations:

DynaZIP is self-contained and fully compatible -- Now in its fifth major generation, DynaZIP reaffirms its leadership in helping software developers incorporate the ability to read, test, create, modify and write industry standard ZIP files, without having to "shell" to a DOS session. The royalty-free DynaZIP libraries can read and write files compatible with the latest version (2.04G) of PKZIP from PKWare, Inc., (another company, not associated with Inner Media). And, because DynaZIP has its own built-in ZIP encoding and decoding logic, PKZIP and PKUNZIP are not used, and need not even be present on the target machine.

Add ZIP to your Windows programs -- DynaZIP allows developers to take advantage of the many benefits of reading and writing ZIP files. Because the super-fast DynaZIP libraries accurately follow the industry standard ZIP format that has evolved, files may be shared with anyone who has a copy of PKZIP and/or PKUNZIP, two popular shareware programs available on most bulletin board systems. The DynaZIP libraries make it easy to work with ZIP files. And since no DOS activity is involved, there is no transition time or screen noise when ZIP/UNZIP operations begin and end.

Supports many environments -- The DynaZIP libraries are available in both 16 and 32 bit versions and include generous sample source code to help you adapt its features to your applications written in C, C++ (including Microsoft Visual C++ and Borland C++), Visual Basic (versions 3.0 through 5.0), Pascal, Delphi, FoxPro for Windows, Visual FoxPro (versions 3 and 5), Paradox for Windows (16 and 32 bit), Microsoft Access (16 and 32 bit), Clarion (16 and 32 bit), and many other languages. Of course, DynaZIP still has all the great features that developers like yourself have come to know and enjoy, things like full background processing, cancelable operations, dual progress monitoring, and much more.

Totally backward compatible! -- Current DynaZip users, don't worry, your software investment is totally safe; we'll never abandon you by creating new, incompatible APIs (unlike some other tools vendors). In fact, ever since version 1 of DynaZip you've been able to easily migrate your applications, usually only requiring small changes and a recompile. The same is true for version 5, and will be true for future versions to come.
