What’s the best program to open a daa file?

I’m trying to open a daa file with power iso and magic iso but i get a message saying that that the file doesn’t have a program associated with it. It tells me to create an association in the folder options control panel which i did already although not sure if i did it in the right way. It seems to me that the correct program should be able to read the file without major obstacles as i’m having now. I really need to open these files any suggestion on how to go about this would be very helpful. Thank you
