Larry, there is an option to assign a password when I zip up a file to email on the distribution lists. There is a box to check yes or no. I am sure I always check the no box, because if I checked the yes box then I would have to assign a password to the file and that has never happened.
Perhaps the original zipper upper assigned a password to it accidently cause now days I usually just write a cover note and forward the email with the zipped song in it.
Larry, it is ok to bother me. I will always try to help
Best to you
