I inadvertently imported files to my system drive 'C' instead of one of my photo drives. I can't find a way to move the folders from within Lightroom. I followed the instructions in Move folders around in Lightroom | but it won't let me click and drag.
I don't know why not. All I got was a Ø indication when I attempted to drag.
I ended up making the physical move in Windows, then finding the new location in Lightroom. Job done. Consider it closed.
