I have a couple of AFCAD questions. I know there are two different formats for AFCAD files (the old AFCAD and the new ADE9). First question is I have always kept my AFCAD files in a seperate folder and added it to scenery as a seperate entry. This was in part to help prevent duplicate entries. First question is this a good idea or should they be kept with the scenery packages they came with. Next question: With the new ADE9 format how does one from having duplicate files (If I have a scenery with an AFCAD type file and it is replaced with one with an ADE9 format and placed them in the same AFCAD file I would assume there would then be a duplicate runway and would this then case issues. This having been said how would one solve this or prevent it from happening, considering the large number of files involved. Maybe this is an issue or maybe not since I am doing a re-install I would like to know before I start installing scenery files.
