When generating .4dz files, 4D uses a standard zip format by default. If you are a software publisher, you’ll be happy to know that 4D v19 R2 added a feature that allows preventing users of your application from seeing the content of the 4DZ, and therefore from being able to modify it.
HOW to proceed?
