Elements is a database. It does not store your photos in a separate location. So, you will be able to import all of the photos stored on your computer into a catalog and you will be able to view and edit them in the Editor. It has been so long since I have used CS6 so I don't know how it handled adjustments to raw files (whether the adjustments are made in the metadata or in a sidecar XML file). Either way, I'm sure Elements will be able to handle them.
