With Adobe DNG Converter, is there any way to automatically delete the original CR2 files as they are being converted to DNG, so that I don't end up with two versions of each file, one with a CR2 and one with a DNG suffix? I could not find this option under the DNG Preferences.
Not in the DNG converter. However, if you use the DNG converter to download your images from the card you can simply convert as they are downloaded. Then all you have to do is format the card in your camera again. If you convert to DNG using Lightroom after the images have been imported you can set your options to delete the original raw file after successful conversion.
Extremely helpful, many thanks!
