A file already exists at this location

Just got the EX2, started coping files from an external drive, opened an App on iPad, started a backup. Then found a folder I was copying from the external drive, was able to click on videos and watch a video. Then I got a message that I need 600MB free space to complete the backup. I deleted few apps but the backup didn’t continue. Restarted the all and now I am getting an error when clicking on Video or Photos - invalid operation - A file already exists at this location or an invalid operation was attempted. Getting the same issue from my iPhone.Any help.
