Can you use the Fox Pro libraries to compress files in Lianja?
we use the Chilkat libraries for a number of purposes in VFP and Lianja. The integration with Lianja is particularly smooth (and described well on the Lianja site). The Zip options available are very handy in various scenarios.
The chilkat extension for Lianja is available for Windows, Linux and MacOS.
There are many feature rich classes specifically built for Lianja including zip/unzip and other compression libraries.
