I use online backup now, but before I would backup on to a DVD+RW disk( with Norton 360). My old computer crashed I restored the new one with the online restore. Apparently I had not backed up my pic's to the online storage. I know they are on the backup disks, yet can't retrieve them. I do not want to restore the entire old backup. When I try to open the DiskId.dat file I get error message Windows can't open this file: then gives me choices to open using Web service to find the correct program. #1 is this safe ,#2 will this open files only to look at them not downlod all?
