Skip if identical

On name collisions:
There is an option of "Overwrite if newer"
Could you add an option of "Skip if identical"

By identical I do mean a byte by byte compare, and not only things like date, time, size, etc.

Thanks in advance if you can!

"Overwrite if different contents" does the same.

I think the option I really need is:

Suffix increment to copy IF CONTENTS ARE DIFFERENT

Where same/different is determined by a byte to byte comparison.

Note in many cases whether a source file is different to a target file of the same name could be determined by only comparing the first few bytes. You only need to find one difference and the files are different.

Another easy shortcut to that would be if the file SIZE is different the contents of the file must be different - without even opening either of the files concerned.

Thanks, I know how it's done.

I'll consider your wish. It looks like something that could/should be done a bit differently.
