Mac or Windows?
What version of the OS?
What version of Lightroom?
Has the import finished? (Converting to DNG can be time consuming.)
Does the destination folder appear in the Folders panel?
Do any of the images show up in the Library grid?
Definitely. Actually, just copied the RAW files, then sent selected
images, converted to DNG's, to 3 different folders on external hard drive.
Only one of those folders remained absent from the left panel.
The images do show up in a folder that Lightroom must have created bearing
the date of download as its name.
Since posting the question I "added" the folder and solved the problem but
still wonder why, after exporting to that folder, the left panel didn't
recognize its presence.
Thanks for any help/clarification.
