best practice - learning DCP

[bsacco]

Is there a feature where you program auto selects the best available picture to save among all the duplicates? That is, scan for the largest file with the most complete EXIF data and ensures it displays a working thumbnail image that has the correct orientation.

If not, can I make this suggestion?

I'm dealing a ton of dupes.

Many of the photos I have do not have exif data available.

Is there a shortcut foolproof way of naming files BEFORE they enter DCP so that the program identifies the files I DO NOT WANT TO KEEP when selecting "Mark by Group"?

Thanks, bob
