I have all my photos in Photos.app. I also maintain them in Dropbox.
My workflow is:
- Import from camera/iPhone into Photos
- Organize photos into albums - some into new albums, some into existing albums.
- Export unmodified originals from Photos to a folder structure that matches the album layout in Photos using File > Export > Export Unmodified Original
New albums are easy. Exporting the entire album is no problem since they are all new files. If I add images to an existing Photos album, I'd like to be able to simply export all of the photos in that album to the Dropbox folder. But if I do that, Photos makes a second copy of the image named "image000(1).jpg". I don't get prompted to overwrite or not overwrite existing files.
Is there a way to have Photos.app prompt me to overwrite existing files instead of creating duplicates? Perhaps a hidden plist setting somewhere I can modify...
