By default, when this key is set to True or omitted, a built application will be generated as a read-only .4dz packed file.
When this key is used and set to False, the built application (Single-user or server part of a Client/Server application) will be generated as a regular Project folder containing only compiled code. This architecture allows the 4D code to apply modifications to the local data model of deployed applications (using commands such as CREATE INDEX, ARRAY TO LIST, or SQL create/alter statements). Keep in mind that these modifications are saved locally and will be lost when the application is updated.
Note: In Client/Server built applications, this key only allows data model modifications for code executed on the server. For optimization reasons, client applications always receive the structure as a read-only, compressed file. Thus the code executed on the client side cannot modify the data model, even if you used this key.
