Question: What are photos with FullSizeRender.jpg filename?
Apple Photos shows number of my photos to be about 26000. An external app, Investigator, and Google Photos count about 46,000. Found out many in Investigator with identical file name FullSizeRender. It seems all photos I edited and cropped have FullSizeRender photo in addition to regular photo with file name ending in .heic or .jpg. Can I delete the FullSizeRender to free up space? How can I do this quickly?
