Cletus,
I store my photos on external hard drives. Because I often find myself taking a photo into Photoshop for additional work, for many images, I end up with not only the original NEF files, but DNGs, TIFFs, etc, that have been altered in Photoshop. And that means the drives fill up.
I was trying to move a folder of images from an almost full drive to an almost empty drive. I know this should be done within Lightroom, but Lightroom crashed on three successive attempts, resulting in a system message, "Lightroom is not responding," along with a progress meter that did not move for several hours. (Lightroom crashing only began with this newest release.)
Out of frustration, I decided to move the files via Finder, thinking I could simply tell LR where the photos had been moved to.
Not so simple. Some photos were able to find their collection, virtual copy, and other such data with no problem. But there are many that just can't find it. A couple can't seem to locate the photos, even though I've told LR where they are. I have one folder that LR indicates only contains 12 photos, while according to Finder, there are 103. But it if I try to import those photos, LR tells me there are no new photos to import.
And that's the problem.
