I downloaded a file with the extension of ".daa" which I was unfamiliar with and didn't know what was, so I stupidly deleted the .daa in the file name and replaced it with .iso. Now I can't change the file extension back to .daa. How in the world would I go about doing such a thing? I can't do it in the "properties" menu when I right click on the file, and simply renaming the file as I did the first time won't work either. Converting the file using PowerISO won't work either as it already is in .daa format but is being identified as a .iso. Am I just screwed?
