I come back, and decide to do a little more work. I go to open the file, and I get this message: Unable to decompress data - the compression format is unknown or its data is corrupted OK. So, is all my data lost?? Or is there a way to fix/recover it?? John Fleming ------------------------------------------------------------------------ Family Tree?? Try Family Shrub.

I got 3 emails in the last 3 days about an identical problem. The code to save GenoPro (.gno) files has not changed in more than a decade. I suspect all of those errors are from SD cards or USB memory drives which are inherently unreliable. Back in the days of floppy disks, I was getting the same kind of emails / support tickets regarding lost files on floppy disks. If you want to see if all your data has been lost, try opening the .gno file with Notepad. If all is blank (typically zeroes) then there is nothing I can do. If you see a bunch of different symbols, then there is some hope some of the data may be recovered. I am curious... do you have other files in the same folder as the .gno file? If so, are those files valid or their contents have been replaced with zeroes the same as your .gno file?
