Where are photo files with extension "HEIC" stores on internal hard disk?
I imported photo files from my iPhone and they apparently are saved on the iMac hard disk in a file format "HEIC". I now want to save the HEIC files to an external CD, However, I cannot find where these HEIC files are stored on my hard disk. I can view them in photos, but cannot find them to export to external media. Any help appreciated. Running Mojave version 10.14.6. Thanks
