Thanks Bill. You explained it so simply that maybe I am not too old to be using a computer after all. If I understand correctly, you said: 1. One cannot post to an FBK file. If I attempt to do so, the new data will, somehow, be loaded on the FTW official file. 2. At the end of a posting session, the system will automatically make the FBK file look exactly like the FTW one. And so, if I thought I was accidentally posting to an FBK, no harm done. I need not worry whether new information got on the proper file, because the automatic back up system accomplishes this at the end of every session. It must be that I was mistaken when I thought one female's record had more information in it than that same lady's other file. I don't need it explained to me, but today I was looking for a list of siblings. High nor low could I find that information but I remembered posting it to her REMARKS. Someone told me to look at the FILE icon on the FBK file, and find the option BACK UP FAMILY FILE. I clicked it, and then went back to my official file, and I located the list of siblings that I knew I had posted some months ago. Don't worry about trying to explain that to me. Seriously, I could not find the sibling list on the FBK file nor on the FTW file. I see that it doesn't matter if I make a mistake. Gratefully Harold Yazoo County, Mississippi
