When capturing images in Lightroom mobile (or when importing them into Lightroom mobile from your camera roll), Lightorom uploads those photographs to the cloud and then downloads them to Lightroom CC on the desktop. By default, the images appear in the Folders panel under a new drive header with the same name as your mobile device. While it’s easy to select and drag the files to another folder, it might be easier to import them directly into your desired folder. To do this, you need to change the default location for your mobile files. Under Preferences > Lightroom mobile, enable Specify location for Lightroom mobile images, click Choose, and navigate to the desired folder.
Note: you can also have Lightroom automatically create folders based on capture date.
