    I spent extra on this so we would have more than enough storage space to put family photos and use for schoolwork. Then as soon as I got the flashdrive back from the photographer, I couldn't open a single file to view any of our pictures. I heard it could be a compatibility issue with Windows 10, but it advertises that it can be used with Windows. Sincerely, Disappointed
