I have just received an MP3 file/recording of a funeral. I want to store it on my Mac and somehow organize the file. As background, I have never used iTunes or any other music app on my Mac because I have never managed to figure them out. I think I may have three or four songs on my iPhone, but quit because I couldn't figure that out either. What I received was an MP3 file as an attachment to an email. I would like to know if there are any folders/files that will not take MP3 files; like I believe some folders won't take jpeg files. I would like to know how to set up a folder that I could put audio files in that are not music. This would be for ease of my locating them by subject in the future. Would appreciate suggestions and/or references to tutorials on audio that is not music. Thank you!
