Update. I just went and pulled my card. There wasn't any additional pics on card and should've been at least pics of me.
Good news is I was able to delete pics. Instead of trying to delete things normally like I do w my phone I clicked on edit and tried deleting that way. They deleted quick
. How do I reformat the card by using the reader? Or do I have to? When deleting all pics do I delete the folder?
Yes, that is correct. You DON'T have to reformat the card every time if you are using it in the same trail camera. I recommending labeling your SD cards, with 1A, 1B, 2A, 2B, etc so that each card is being used in the same camera.
Now you can use cards across several different trail cameras, the trail cameras will just create another folder on the sd card, but sometimes it causes formatting issues with the card. So to be safe, we suggest to keep the same card for the same camera. If you notice on the cards, you have multiple folders, that is because it has been used on several different trail cameras or several different cameras, or either.
You can't reformat the card with the reader. That has to be done on a computer for now. Some trail cameras have that option of reformatting the sd card, some don't.
I hope this answers your questions!
