In addition to Custom Software Development and other Services, Absolute Software, LLC also offers Xbase++ add-on products.

XbZLib

XbZLib, a free, Open Source add-on product for Xbase++ developers, allows Xbase++ applications to create and manipulate Zip files and compress data and files in memory or on disk. The associated AGPZip executable is a demo implementation of (some of) the XbZLib features, emulating the PkZip and PkZipFix DOS programs.

The latest version of the XbZLib Source Code, including pre-compiled DLLs, can be downloaded from here. A new version of XbZLib with an updated Online Help will soon be released.
