I used the aperture import tool to import 20,000 pictures.
They are in about 900 folders that are labeled by date.
I'd like my folders to mirror my albums.
So is there a way to look at an album in LR and then select the photos in that album and move them to a new folder within the finder?
It is basically a simple drag and drop operation in the Library module.
If the destination folder does not exist, highlight the images to move, create the folder in the Left pane Folders tab, say "yes" to the "move highlighted" prompt.
I have never tried that, but I can't see why not.
Keep in mind that your collection may span multiple source directories.
