@Mammmood - I’ve used some of those programs myself. I want to remind you, however, that you are not actually converting the CDA file itself, despite the name of the program.
The CDA file is just a pointer to the audio track. You are converting the track itself. These distinctions are probably unimportant, as long as you follow the instructions and just use the program, but I thought I’d point it out.
Sometimes people think their program is not working because they are trying to convert the CDA file and not the audio track.
