My airfoil plot programs can accept either one as long as long as they are in true COR or DAT format. Trouble is that some of the airfoils with a COR or DAT file naem extension are not really in that format. Before going to a lot of work, I would try renaming a copy of the data file with a .cor file name extension and see if it will run. If not, then I have been able to edit some airfoil data files in Excel and get them to work. As a last resort, I have used the Data Entry module to type in the coordinates if nothing else worked and I really wanted to plot that particular airfoil.
