Today someone asked how I had sent them an email which played a midi tune. I explained ( the format-background-sound thingy) and then the questions got way beyond my depth. I have been asked if wav and mp3 files can be sent the same way, as a 'background' rather than a file attachment, I said I didn't think so, but I don't know. The other question was where exactly is the midi file I sent that plays on his computer? At first I guessed it was stored in some obscure outlook express folder where he could find it if he looked. After doing a hard drive search on my computer and not finding any unusual folders with *.mid files I am now thinking that the actual coding of the midi is part of the email body?
My brain hurts please help!
