I'm trying to get a list of all the family table instances for all of the parts in a directory so that I can determine any conflict before moving them to intralink. For example a conflict might be where two parts have the same instance name or a part has an instance that also exists as a generic, etc.
I've done this before using a Trail file. I also updated the instance tables for every part (as part of the trail file). This gave me the directory_name.idx file containing all of the family table instances.
To get the complete trail file, I used a UNIX shell script to take a list of parts and create the needed trail file. If your not using UNIX, I'm not sure what you would use to create your final huge trail file.
