That stopped working with v11. 4D has made it required to have a structure file that matches the data file to be able to access tables and the data in those tables. So you are going to have to find a structure file for this data file. They have a built in “WEDD” resource — to use terminology form the “old days” — in the data file and structure file that must match. Chuck mentioned trying to open the data file on 4D Server and use SQL, but you would still need a structure file that matches the data file in order to open it with 4D Server. So if you don’t have any structure file at all, you are stuck. If you don’t have a structure file, you ain’t getting access to the data in the data file without a crazy, ridiculous amount of work and effort. No easy way to do it.
