Create folder hierarchy on your external hard drive (to match screen shot below) to store your assets.
Once your folders are created, just add media. It is very important that you
DO NOT MOVE OR RENAME YOUR FOLDERS OR FILES after you set up.
Final Cut Pro and Lightroom use pointer files that connect your applications to your media.
If you move or rename, you will break the path and you will need to re-link to your files.
Add subfolders in photo, audio and video folder for each assignment that you shoot!
