I do that quite successfully for some time now. My question is, would that help when you have 80 locos? I found that when you have too many under one driver set up folder, things go a little out of nonsense. But if you divide them into 2 or 3, I found that it runs better or normally (something related to the timeout issue, so certain things on the program don't have to run through a long list of locos. Maybe is my perception, but dividing locos and consists into subfolders makes more sense, if anything for the sake of having a neat file and folders layout.
