Ok this is pretty old but I have decided that it is bugging me enough to post something about it, I can not delete/move/rename my 2 old Cata:DDA template files back in 0.5. For whatever reason they can not be detected but they are still there!
Try refreshing windows explorer (F5 I think?). If that doesn’t work open up notepad and save a new blank file. Rename it to exactly the same thing as that file and move it into the folder. With any luck it should overwrite the old location and you should then be able to delete it properly.
I have tried refreshing many times, also I tried to do the other thing and
HUSTON, WE HAVE A PROBLEM.
