Following UFT instructions to backing up UFT projects to a 31/2 Floppy Disk or to a Zip disk I seem to have no problem. When I insert either of these disk to retrieve the project on the disk I get a box captioned "Microsoft Backup" containg a red circle with an X within. The message reads "This file name is not valid. The file must have the extension .SET. How do I retrieve this backupped information from the disks?
