Russ; I can have 4 pictures in my Media Folder and in the Family Page where the names are. My family file is 27,982 KB. This doesn't change when I put pictures in the Media Folder. The system Info under the Help tab says 1.92 GB of available RAM. I am under the impression that FTM uses the computer's RAM to load/open my file because the message I get when I create the book is "Not Enough Memory left to Generate Your Book". so they must be talking about computer memory (RAM).
