I have over 80,000 photos that have been given proper EXIF keywords but Google Drive requires data in the Description for it to be searchable in their online app. I need to copy the contents of the Keywords entry to the description on this mass of photos that goes deep into sub directories.
Copy EXIF meta data from the Keywords to the Description on a huge amount of photos in sub folders
exif;file metadata
Using ExifTool you could just run:exiftool -TagsFromFile file.jpg '-Keywords>Description' file.jpgYou can find more info in the manpage for exiftool.
