Only sorts by Created Modified or Accessed. MUST SORT BY FILENAME. Still unable to sort photos by Filename. This is absolutely critical as scanned images have the incorrect capture date. Additionally when you copy to a new computer you get a whole new created date although the modified date is correct for digital images but NOT for scanned images. I have spent a considerable amount of time using batch processing to get the correct Filenames with correct dates, etc. IT IS CRITICAL TO ADD TO THE SELECTION AT THE BOTTOM THE ABILITY TO SORT BY FILENAME IN ADDITION TO JUST USING THE EXIF CREATED, MODIFIED AND ACCESSED DATE.
