Add ability to rename Destination Folder file names to match the source. Windows considers Filename.txt and FILENAME.txt to be the same file, so Replicator doesn't even notice the change.
As I read the books I change the author's name to ALL CAPS, which just indicates that I have read that particular book. I back-up these books on an external drive. The capitalization is not changed on the back-up drive, it is still 'Bob Jones' rather than the new 'BOB JONES' as on the laptop's drive.
Perhaps a job configuration for case-sensitivity? Some destinations might be case sensitive already and so a name change ends up copying the file again to the new name (like if the destination is on a Linux server... not exactly a common use case). Anyway, think before you program, Joe.
