No, those two DB files, they currently using just under 7GB for me, i have moved on different disk long time ago. edsmsystems.json is different file.
OH - Look I learned something!
I honestly thought when I put the database in a separate drive that all the data was held there. Now I see that I have 7.17GB in that separate database but still have 7.78GB in the AppData tree.
That is both confusing and a bit annoying. So apologies for being wrong (not for the first time).
