THM files when taking pictures off SD card - Kodak AZ252

To get the pictures onto my desktop I remove the card, plug it into my SD slot on the computer. The folder that opens has thumbnail files next to every picture. I have to click every individual file to delete it as they are all in numerical order. Or, select each picture and drag it into another folder to separate them from the thumbnails. Most infuriating.
