RM7 will import the Description, but not the Date using this method. Thanks for the idea about exporting to the other FTM destinations. I updated my original post.
Hello a user at the Ancestry Forum did a test with FTM2012 and FTM 2014.
"I have have both FTM2012 & 2014. Neither exports media Date. Ditto, Category. Strangely, 2012 exports Description, but 2014 doesn't. (Apparently FTM-Mac3 does, too?)."
