Photoshop Elements :: Importing Folders Into 11?

I've had Elements 11 for some time and can't use it as I can't seem to find a way to import an existing folder structure of images. It imports it flat, with every subfolder and parent folder listed on the same level, so my organisation is shot to hell. I'm sure it's me being dumb, (but in fact it's Elements being incredibly un-intuitive) but how to import an existing folder structure with many images, retaining the structure after import? Actually thinking about it, I can barely remember how to import at all, I found it quite difficult to achieve and I think I might have drag and dropped some files?
