Changing my way of using DTPO for research

Bill, I am rethinking my approach to DTP and I found your post quite helpful. However, it’s two years’ old, so I thought I’d check. Currently, I have multiple data bases, several of them in the several-GB range. They are indexed because I thought that would reduce RAM issues. That seems not to be the case. If so, I will move back to an “imported” approach. What is the best way to do so while retaining the A.I. information?
