It is not exactly the same, as you write yourself later. The difference is that a reimport of the folder is needed to synchronize the film roll with the folder. Therefore, a different, "new" name is justified. I guess most people would expect a folder concept within dt to reflect the state on disc all the time, meaning if I delete an image outside dt this change would immediately show up inside dt, what is not the case.
