I have a folder where there are many pictures taken with my iPhone. Turns out that half of them are JPGs and half of them were supposed to be HEIC format.
For some reason, all pictures in this folder are with JPG extension, check this image: https://imgur.com/a/9D6ScZ4
First, I thought that other JPGs were corrupted files, as you can see in the image above that I got an error when I try to open them. Then, I realized they were supposed to be HEIC and not JPG, because they were Apple Live Photos. When I manually renamed couple of those JPG files that were not opening to HEIC format, they could open correctly as a short video, because they were live photos.
My question is: Is there a way to find all these false JPG files that do not open and rename them from .JPG to .HEIC? I can't just rename all JPGs to HEIC because the other pictures are not live photos.
