I have gotten helpful suggestions from this list concerning the computer. Obviously I was born 50 years too soon to adapt to this tool. I use FAMILY TREE MAKER as a handler file to hold my data. I picked the name FISHTREE as my original start. I have long seen another file that I did not instigate by the name of FISHTREE..FBK. Obviously this latter file is some sort of self generating back up file. On occasion I have found myself posting to this backup file. I presume that means that some new data is not going to FISHTREE. Today I did some looking and I found that some of my latest finds are indeed, on the backup file, but not on the regular, basic file. And perhaps vice versa. Is there someway that I can make certain that both files have all of the identical information on them? Gratefully Harold Fisher Yazoo City, Mississippi
