Maybe I'm missing something, but when you tell Lightroom to import photos using the "reference files in existing location" option, isn't that supposed to leave the files in their original folder? When I import using "reference files in existing location", Lightroom is moving my original files to a new folder. For example, I import all the files that are in this folder:
And after the import Lightroom has moved all those files from my original folder to this folder:
The original folder (F:\Photos\10D\02-0500) remains, but is empty. What's going on here? I don't want Lightroom moving my files from my carefully organized existing folder structure.
