I have several files from my ancient iMac G3 that have no file extensions. They were from a text program that also recorded voice, and read text. It came with the computer, but that was 2 computers ago, and I have no idea the program name, or file extensions.
Each file had an audio track in it of my daughter as a child, and I would like to be able to convert them, or at least hear them. How can I listen to those audio files ?
