How do I extract data from a 4D database?

Question

A client of mime has an old program running on 4D. I am not familiar with this format, but I have 4 files; a .4DC , .rsr , .4DD and one .4DR file.

I suspect that the data is in the .4DD file. How can I extract the data?

Answer 1

If the 4D application does not have an export function in it then you need to go to the developer to open up the data. Data in 4D applications is accessible only to the application that created the data file. This allows self contained applications to remain proprietary. ODBC connections are great when you have access to the source code, which then lets you separate the data from it's application.

This might not solve your problem, but I hope it explains how the 4D.com product works.
