Show Filename Extensions

By default Mac OS X will hide filename extensions. But these can be useful. To reveal them, go to Finder Preferences, Advanced and look for “Show all filename extensions.” Now you should see the full filename for each file. This is also where you can turn off the warning you get when changing the file extension.

    I did it and thank you. I agree it is nice to see the extensions since I come from Windows and they were important there too.......
    Claire - Love your help....
