I am here because I am trying to put "mp3" at the end of the audio files that do not have the mp3 extension. But when i try to place it by means of an action the file is also without extension because it leaves a point after mp3. For example:
Frank Sinata - Hello.mp3.
This means that the file is also left without an extension.
I tried this in the format string: %_FILENAME%.mp3
How can I add .mp3 to all the files that don't have it and that look good?
