I have a camera roll folder with a lot of photos in it. The folder is flat with no sub-folders. I want to move these photos into an existing structured hierarchy based on year and month e.g. %Y\%m\. I know how to do this, however, if it finds a file with the same name I want it to check the destination file's size against the file that is being moved and only move it if the source file is bigger, otherwise, the file should be ignored (and ideally the source file should be deleted as this is a move).
Thanks
