Ah ok great. Thanks for the quick reply. One other question. I won a raspberry pi 3 model b in a giveaway. It came loaded with a bunch of games and such so I wanted to make a copy of the image. Bought the exact same SD card exact same size. Made a backup of the image but when I tried to flash it to the new card it was just shy of enough space. Any idea as to why that is when its the same brand/size sd card?
