I've plugged my iPhone 5, v 8.1.3 into my WIN7 laptop. in the DCIM folder there are several subfolders, some of which contain lots of 'Local Disk' files. What are these? I suspect they are photo or collections of photos. I have hundreds of photos and videos I'm transferring and have not yet gone through the iPhone one-by-one to compare whether all the photos transferred.
So, what are these 'Local Disk' files?
