You do have to load the file that way .
I don't know if you will see an advantage if you are not having any issue's . I have done mine and watched the video's and on page 20 of our manual it tells ya just how to do it .
Do use a empty card or a used one that you have just formatted and if going by the steps in the manual where it says ..Turn on the camera... it means to power up bird. I always leave my camera on all the time . Do wait till the light turns green after the yellow flashing before you do anything else as I have heard you can brick the camera . I have done this several times with never an issue but was just saying !
Do watch several video's on it and do read what it says in the manual but if it's working fine ..why mess with it !
