I am not sure what you are doing but I will tell you what to do in any case:
Buy a memory card reader (make absolutely sure that your camera's memory card is compatible with the card reader you bought) be that SD, Micro SD or CF
Now insert the memory card into the card reader and plug the card reader into the pc.
Open the folder from my computer if autoplay is switched off
Otherwise just open the folder (once)
There should be another folder now, you copy that folder
Paste it where ever you want your pictures to be (after it's done open that folder and make sure it copied correctly)
By that I mean all your photos.
When you are done with that, enjoy your photos that are now on the computer.
You may now format the memory card and use it again.
You're welcome
